Step-by-step explanation:
The floor of a rectangular cage has a length 4 feet greater than its width, w. James
will increase both dimensions of the floor by 2 feet. Which equation represents the
new area, N, of the floor of the cage?
Answers
Answer:
x² + 8x + 12
Step-by-step explanation:
Area of a rectangle = length × width
Original dimensions:
Width = x
Length = x + 4
James will increase both dimensions of the floor by 2 feet
New dimensions:
Width = x + 2
Length = x + 4 + 2
= x + 6
Area of the new rectangle = length × width
= (x + 2) × (x + 6)
= x² + 6x + 2x + 12
= x² + 8x + 12
Equation which represents the
new area, N, of the floor of the cage = x² + 8x + 12

where a , b and c are integers
here we have an equation
so we first multiply the complete equation by 5 to get rid of the fraction
Now subtract 3x from both side to get the required standard form

In the diagram below, $\angle BAC=24^\circ$ and $AB=AC$.
If $\angle ABC=y^\circ$, what is the value of $y$?
Answers
Answer:
y = 78°
Step-by-step explanation:
Since both bases are equal
180-24 = 156
156/2= 78°
The measured value of y is 78 degree.
What is Angle sum property?According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. A triangle has three sides and three angles, one at each vertex. The sum of the interior angles in a triangle is always 180o, regardless of whether it is acute, obtuse, or right.
We have a triangle ABC.
As, the side AB = AC.
We know that Angle opposite to equal sides are also Equal.
So, <ABC = <ACB = y
Using angle sum property
24 + y + y = 180
24 + 2y= 180
2y = 156
y = 156/2
y = 78

Which can be represented by the expression 17 – 2x? A. 17 less than twice a number B. the difference between 17 and twice a number C. a number x squared, subtracted from 17 D. 17 less than a number x squared
Answers
Answer:
B.
Step-by-step explanation:
If x is a number, then twice a number is 2x. The difference between 17 and 2x is 17-2x.
Common Error:
A. says 17 less than twice a number. Since it is 17 less, it is 2x-17 not 17-2x.

A bicycle tire has a diameter of 70 centimeters (cm). What is the circumference of the tire? Use 3.14 for pi. Round your answer to the nearest centimeter.
Answers
Answer:
220
Step-by-step explanation:
70*3.25=219.8
Answer:
220 centimeters
Step-by-step explanation:
To find the circumference of a circle, use the formula [tex]C=2\pi r[/tex], where C is the circumference and r is the radius. Substitute our values in. Remember that the radius is half of the diameter, so it is 35.
[tex]C=2\pi r[/tex]
Plug in the radius of our tire.
[tex]C=2\pi (35)[/tex]
Simplify.
[tex]C=6.28(35)[/tex]
[tex]C=219.8[/tex]
The circumference is 219.80 cm. Round this up to 220 cm.
Good luck ^^

It moves in a straight line starting from rest. It travels with a constant acceleration for 3 seconds reaching a velocity of 4 m/s. Then it slows down with a constant deceleration of 0.5 m/s squared for 4 seconds before stopping what is the total distance travelled by the toy car?
Answers
Answer:
The total distance traveled by the toy car is 14 m
Step-by-step explanation:
Given;
initial velocity of the car, u = 0
final velocity of the car, v = 4 m/s
time of motion, t₁ = 3 s
constant deceleration of the car, -a = 0.5 m/s²
time of motion, t₂ = 4 s
The total distance traveled by the car, is the area of triangle ABC (check the image uploaded).
[tex]Total \ distance = Area = \frac{1}{2} |BC| \times H\\\\Total \ distance = \frac{1}{2} \times 4\times 7\\\\Total \ distance = 14 \ m[/tex]

of her supply of cranberries to make granola. If Melanie uses 7 pounds of cranberries, how many pounds of cranberries are in her supply?
Answers
Answer:
She has 9 pounds
Step-by-step explanation:
Given
[tex]Bread = \frac{1}{3}[/tex]
[tex]Granola = \frac{4}{9}[/tex]
[tex]Used = 7[/tex]
Required
The total in her supply
Represent the cranberry with c.

Solve 252x−1=400 for x.
Which answer shows the correct steps?
Answers
X=400/252
Answer:
1.75
Step-by-step explanation:
252x-1=400
First we need to isolate the x in one side of the equation
Lets add 1 to each side of the equation to get rid of -1
252x=441
now we divide 441 by 252 to get x
x=1.75
UPDATE
The owner of the question said its supposed to be 25^2x -1 =400
ok lets do this
25^2 * x=401
625x =401
