The answer would be 20
A squares sides are equal and there are 4 of them so you take 80 (the total perimeter) and divide that number by 4 (number of sides) and you get 20
Answer: a) 10!/7!

Answer:
I think it's A
Step-by-step explanation:
225x + 400 ≥ 2200
225x ≥ 1800
x ≥ 8
4 = (-8) + 3x

3x - 8 = 4
Add 8 on both sides to isolate the x:
3x = 12
Divide both sides by 3:
x = 4
