Answer: (x - 1)(8x +5)
Step-by-step explanation:
With the equation 4x, the x represents side length. Since we are given side length of 5/7, then the equation becomes
perimeter = 4 × 5/7
p= 20/7
p= 2 6/7 units
First isolate
by subtracting 1 from both sides of the equation.
That gives you
.
From here, since x is being divided by 2, multiply both sides of the equation by 2.
So <em>x = 10</em>.
