Answer:
B
Step-by-step explanation:
Here, we are told that the rectangle is enlarged by a factor of 6, we now want to calculate the new area of the said rectangle.
Now, for the rectangle to have an area of 20, mathematically the area of a triangle can be calculated using the formula L * B
where L is the length and B is the breadth
our product here is 20, so any product that gives 20 would be a good fit as the value of the width and length of the rectangle
So, let’s say the sides measure 5 inches by 4 inches
Enlarging these by a factor of 6, we have 30 inches by 24 inches
The new area of the rectangle would thus be ;
30 inches * 24 inches = 720 inches^2

b

Answer:
x = 50
Step-by-step explanation:
You are correct.
x + m<PQS + m<PSQ = 180
m<PQS = m<QRT = 70
m<QST + m<PSQ = 180
120 + m<PSQ = 180
m<PSQ = 60
x + 70 + 60 = 180
x + 130 = 180
x = 50

khan academy is giving me only this explanation but won't go into detail and I cannot understand it for the life of me. how do I know what number to multiply both variables by? what exactly does expanding the parentheses mean? help
Answer:
12 - 4i
Step-by-step explanation:
-2i ( 2+6i)
Distribute
-2i * 2 + -2i *6i
-4i - 12 i^2
We know that i^2 = -1 so replace it
-4i - 12(-1)
-4i + 12
Then put in the order a+bi where the real number comes first and the imaginary number comes last
12 - 4i

Drag vertices B and C of the triangle. Then, conjecture about the relationship between angle measures and side lengths in a triangle.
If the angle measure is the largest of the triangle, what do you know about the side opposite?
It is the length.
If a side is the shortest of the triangle, what do you know about the angle opposite that side?
It is the degree measure
Answer:
1. longest
2. smallest
For the triangle mentioned here, the following is what will be obtainable based on the conjecture about relationship between sides and angle measures of a triangle:
You will know that for the largest angle measure, the side opposite the angle will be the longest side.You will know that for the shortest side in the triangle, the angle opposite it will be the smallest angle measure.Recall the conjecture about the relationship between the sides and angles of a triangle:
The largest angle in a triangle always faces the longest side of the triangle.The smallest angle in a triangle always faces the shortest side of the triangle.Thus, for the triangle mentioned here, the following is what will be obtainable based on the conjecture about relationship between sides and angle measures of a triangle:
You will know that for the largest angle measure, the side opposite the angle will be the longest side.You will know that for the shortest side in the triangle, the angle opposite it will be the smallest angle measure.Learn more here:

Complete the factorization of 3x ^ 2 - 10x + 8 3x^ 2 -10x+8=(x- Box x-4)
Answer:
[tex]3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})[/tex]
Step-by-step explanation:
The general form of a quadratic polynomial is given by:
[tex]ax^2+bx+c[/tex] (1)
You have the following polynomial:
[tex]3x^2-10x+8[/tex] (2)
In order to complete the factorization you can use the quadratic formula, to obtain the roost of the polynomial. The quadratic formula is given by:
[tex]x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex] (3)
By comparing the equation (1) with the equation (2) you obtain:
a = 3
b = -10
c = 8
Then, you replace these values in the equation (3):
[tex]x_{1,2}=\frac{-(-10)\pm \sqrt{(-10)^2-4(3)(8)}}{2(3)}\\\\x_{1,2}=\frac{10\pm2}{6}\\\\x_1=2\\\\x_2=\frac{4}{3}[/tex]
Then, the factorization of the polynomial is:
[tex]3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})[/tex]

How far around is the entire perimeter? Round your answer to the nearest hundredth.
Answer:
P = 45.16 meters
Step-by-step explanation:
Let the perimeter by P
31% of P is 14 meters
P*31% = 14 meters
Change to decimal form
P*.31 = 14
Divide each side by .31
P*.31/.31 = 14/.31

Let m = 2x+3
m^2 - 4m - 12 = 0
Factor
(m-6) (m+2) = 0
Using the zero product property
m-6 = 0 m+2 =0
m = 6 m = -2
Substitute m = 2x+3 back into the equation
2x+3 = 6 2x+3 = -2
2x = 3 2x = -5
x = 3/2 x = -5/2

Answer:
I think the answer is C. 324 but i'm not sure. lemme know if i'm wrong and what the correct answer is
Step-by-step explanation:
The area of the given Circle C is; 324π
What is the area of the circle?
From the attached diagram, we see that;
WX is the radius of circle X and is equal to 8 units
Similarly, ZY is radius of circle Y and is equal to 10 units.
Thus, diameter of circle X = 8 * 2 = 16 units
Diameter of circle Y = 10 * 2 = 20 units
Thus;
Diameter of circle C = 20 + 16 = 36 units
Area of Circle C = π * 36²/4

Assume total number of student = 100%
So, probability that both of them use it.

(x-5)(x+1)
Substitute with One Solution
2x -y=-11
6x + y = 3
Answer:
x=1, y = -3
Step-by-step explanation:
2x -y=-11
6x + y = 3
Add the two equations together
2x -y=-11
6x + y = 3
--------------------
8x = 8
Divide by 8
8x/8 = 8/8
x= 1
Now find y
6x+y = 3
6(1) +y = 3
6+y =3
Subtract 6 from each side
6+y-6 = 3-6
y = -3

Franco made a dozen muffins for his party. Upon taking them out of the oven,
he noticed that 2 of the muffins were badly burned. Franco served of the remaining muffins.
10
Which equation shows the fraction of the non-burned muffins that remains?
Answer:
Option B.
Step-by-step explanation:
This question is incomplete; find the complete question with the attachment.
Franco made number of muffins = a dozen
A dozen muffins = 12 muffins
Number of muffins were burned = 2
Remaining muffins = 12 - 2 = 10
Franco served 7 of the remaining non-burned muffins,
Fraction of muffins served = [tex]\frac{7}{10}[/tex]
Remaining muffins = 3
Fraction of remaining muffins = [tex]\frac{3}{10}[/tex]
Fraction of remaining non-burned muffins we can get from,
[tex]\frac{10}{10}-\frac{7}{10}=\frac{3}{10}[/tex]
Option B is the correct equation.

Step-by-step explanation:
Is this the one you needed??
how many cylindrical glasses 6cmin diameter and 10cm deep can be filled from cylindrical jug 10cm in diameter and 18cm deep
Answer:
Step-by-step explanation:
So we need to divide the volume of the cylindrical glasses by the cylindrical jugs to see how many we can fill.
The equation to find the volume of a cylinder is Height*Area of Circle
To find the area of a circle is: [tex]\pi r^{2}[/tex]
In this senario "r" (radius) is 3 (d/2)
Volume for cylindrical glass:
hx[tex]\pi r^{2}[/tex]
= 10x 3.14x 3^2
= 10x3.14x 9
= 282.6[tex]cm^{3}[/tex]
Now for the cylindrical jug: r= 5 and h=18
hx[tex]\pi r^{2}[/tex]
= 18x3.14x5^2
= 18x3.14x25
= 1413[tex]cm^{3}[/tex]
Now finally we divide them:
1413/282.6
= 5
So they can fill 5 cylindrical glasses :)
