the values of x will make the perimeter at most 58 inches is 14 inches
Step-by-step explanation:
One of the side = 15 inches
The other side = x inches
Perimeter = 58 inches
formula for perimeter: P = 2(length + width)
We assume the length = 15, width = x
58 = 2(15 + x)
The question says at most 58 inches. This is depicted as ≤ 58
It becomes:
2(15+x) ≤ 58
Open the bracket:
30 + 2x ≤ 58
collect like terms:
2x ≤ 58 - 30
2x ≤ 28
Divide through by 2:
x ≤ 28/2
x ≤ 14
Therefore, the values of x will make the perimeter at most 58 inches is 14 inches
