Answer:
Unitary cost= $37.34 = $37
Step-by-step explanation:
Giving the following information:
Number of tires= 8
Total cost= $298.75
<u>To calculate the unitary value of each tire, we need to use the following formula:</u>
Unitary cost= total cost / number of tires
Unitary cost= 298.75 / 8
Unitary cost= $37.34 = $37
The squiggly lines and the 2 straight lines through to sides of the pentagon mean that they are congruent (equal in length).
So, to find the perimeter of a regular polygon, you add all of its sides together.
So, the perimeter= 4x-2+x-2+x-2+x+2+x+2
To simplify it, add all of the x's together.
4x+x+x+x+x=8x
Perimeter=8x-2-2-2+2+2
-2-2=-4-2=-6+2=-4+2=-2
Perimeter=8x-2
Reach out to me if you have any questions. I'd be glad to help! :)
L = X
w = X - 8
P = 52 cm
P = 2l + 2w
52 = 2(X) + 2(X - 8)
52 = 2x + 2x - 16
52 + 16 = 4x
68 = 4x
68/4 = 4x/4
17 = X.
The length of the rectangle is 17 cm.
W = X - 8
W = 17 - 8
W = 9 cm.
The width of the rectangle is 9 cm.
