<span>a=7b+8c+9d-10
a = 8c + 16d - 10
solve for c then
8c = a - 16d + 10
c = (</span>a - 16d + 10) / 8
or
c = a/8 - 2d + 5/4
Since the perimeter is the sum of the length of all sides we multiply width and length by 2 and then add them together

Answer:
B.
Step-by-step explanation:
use distributive property
4*x + 4*3 = 4x+12
Standard form is Ax + By = C, or By = C - Ax.
Dividing both sides by B, we get y = C/B - (A/B)x
Here the y intercept is C/B, and the slope is -A/B.
