Which one?
A. B. C. Or D? ​

Answer:

The length of the rectangle: 3x

The width of the rectangle: x

Theres 2 lengths and 2 widths for every rectangle.

So the full perimeter is 3x+x+3x+x = 8x

8x;

= perimeter

= 40 inches

8x=40

x=40/8

x=5 inches

Length is 3x, substitute in for x

l = 3(5)

Divisibility Rules: 2, 3, 4, 5, 6, 9, and 10

A number aa is divisible by the number bb if a \div ba÷b has a remainder of zero (00). For example, 15 divided by 3 is exactly 5 which implies that its remainder is zero. We then say that 15 is divisible by 3.

In our other lesson, we discussed the divisibility rules for 7, 11, and 12. This time, we will cover the divisibility rules or tests for 2, 3, 4, 5, 6, 9, and 10. Believe me, you will be able to learn them very quickly because you may not know that you already have a basic and intuitive understanding of it. For instance, it is obvious that all even numbers are divisible by 2. That is pretty much the divisibility rule for 2. The goal of this divisibility rules lesson is to formalize what you already know.

y=145°, x=35°

Step-by-step explanation:

y = 145° (vertically opposite angles)

x + y = 180°(linear pair)

x + 145° = 180°

x = 180° - 145°

x = 35°

Answer:

The average rate of change is 1 over 3, or just 1/3. The y-values change 1 unit every time the x-values change 3 units, on this interval!

We want to find the average rate of change of the graph on the interval 1 ≤ x ≤ 3.

The correct option is B: -4

We know that for a given function f(x) the average rate of change on the interval a ≤ x ≤ b is given by:

[tex]\frac{f(b) - f(a)}{b - a}[/tex]

Here we have the interval  1 ≤ x ≤ 3, and by looking at the graph we can see that:

f(3) = 1

f(1) = 9

Then the average rate of change is:

[tex]\frac{1 - 9}{3 - 1} = -4[/tex]

So the correct option is B.

The expression that is equivalent to the given expression is -x+9y−5. The correct option is 2. −x+9y−5

From the question,

We are to determine the expression which is equivalent to the given expression.

First, we will simplify the given expression

The given expression is (12x−5y−1)+(17y−4−13x−3y)

The expression can be simplified as shown below

(12x−5y−1)+(17y−4−13x−3y)

12x−5y−1+17y−4−13x−3y

Collect like terms

12x−13x+17y−5y−3y−4−1

This becomes

-x+9y−5

The simplified expression is -x+9y−5

Hence, the expression that is equivalent to the given expression is -x+9y−5. The correct option is 2. −x+9y−5

Answer:

s = 6/7 yd

Step-by-step explanation:

Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.

The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.

Please specify? I don't understand what the question is supposed to be.

Answer:

In algebra, a quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.

Answer:

The area of the shaded region is (540 - 65.25pi) in²

Step-by-step explanation:

The remaining part of the question which is an image is attached below.

Step-by-step explanation:

To determine the area of the shaded region, that will be the difference between the area of the rectangle and the sum of the areas of the three circles.

First, we will determine the area of the rectangle, which is given by

Area of rectangle = Length × Breadth

In the figure, Breadth = 18 in

and Length = 12 in + 9 in + 6 in + 3 in

∴ Length = 30 in

Hence,

Area of rectangle = 30 in × 18 in

Area of rectangle = 540 in²

Now, we will determine the areas of the circles one after the other

For the smallest circle

From the figure, the diameter of the smallest circle is 6 in

From Radius = Diameter / 2

Hence,

Radius of the smallest circle = 6 in / 2 = 3 in

Area of a circle is given by

Area of circle = πr²

∴ For the smallest circle

Area of the smallest circle = π×3² = 9π in²

Hence, area of the smallest circle is 9pi in²

For the circle in the middle

Diameter of the circle in the middle is 9 in

∴ Radius of the circle in the middle = 9 in / 2 = 4.5 in

For the area of the circle in the middle

Area of the circle in the middle = π × 4.5² = 20.25π in²

Hence, Area of the circle in the middle is 20.25pi in²

For the largest circle

From the figure, the diameter of the largest circle is 12 in

Hence, radius of the largest circle = 12 in / 2 = 6 in

∴ For the largest circle

Area of the largest circle = π×6² = 36π in²

Hence, area of the largest circle is 36pi in²

Sum of the areas of the three circles = 9pi in² + 20.25pi in² + 36pi in²

Sum of the areas of the three circles = 65.25pi in²

Now,

Area of the shaded region = Area of the rectangle - Sum of the areas of the three circles

∴ Area of the shaded region = 540 in² -  65.25pi in²

Area of the shaded region = (540 - 65.25pi) in²

Hence, the area of the shaded region is (540 - 65.25pi) in²

Answer:Similar triangles are easy to identify because you can apply three theorems specific to triangles. These three theorems, known as Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS), are foolproof methods for determining similarity in triangles.

hope this helped! (if ya did a brainliest that would really help)

The three ways to determine if two triangles are similar are Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS)

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Two triangles are similar if they meet one of the following criteria. : Two pairs of corresponding angles are equal. : Three pairs of corresponding sides are proportional. : Two pairs of corresponding sides are proportional and the corresponding angles between them are equal.

Also, Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles. If two or more figures have the same shape, but their sizes are different, then such objects are called similar figures.

The three theorems to identify similar triangles are, Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS)

That explained as, two pairs of angles are congruent (AA) (2) two pairs of sides are proportional, and the included angles are congruent (SAS), or (3) if three pairs of sides are proportional (SSS).

Step-by-step explanation:

Answer:

They will have never paid the same amount

Step-by-step explanation:

the equation 3+2x=5+2x simplifies to 3=5 which is not a true statement

Carmen always pays a higher amount than Maria where the fee for each lesson is the same for both Carmen and Maria.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Maria:

Yearly fee = $3

Fee per lesson = $2

Carmen:

Yearly fee = $5

Fee per lesson = $2

The equations to represent the amount A after x lesson:

Maria:

A = 3 + 2x

Carmen:

A = 5 + 2x

The number of lessons at which both have paid the same amount:

3 + 2x = 5 + 2x

0 = 2

There is no solution.

Thus,

Carmen always pays a higher amount than Maria where the fee for each lesson is the same for both Carmen and Maria.
