Answer:
x = -6.8
Step-by-step explanation:
3/4 (x) − 1.72 = −6.82
Add 1.72 to each side
3/4 (x) − 1.72+1.72 = −6.82+1.72
3/4x =-5.1
Multiply each side by 4/3 to isolate x
4/3 * 3/4x = -5.1 *4/3
x =-6.8
Perimeter is all of lengths of the sides added up. We know a square has four sides, all the same length. Therefore each side must be exactly ¼ of the perimiter.
So that's (16x-20)÷4
We can simplify that, by dividing both 16x and 20 by 4 to get (4x-5)
So the length of one side is (4x-5)ft
