The equation has to be set to something otherwise it is just an expression. I will assume that you mean 3x+60=0 in which case x equals negative 20
Answer:
Step-by-step explanation:
length = 25 in
Perimeter = 86 in
2*(length + width) = 86
2*(25 + N) = 86
Divide both sides by 2
25 + N = 86/2
25 + N = 43
Subtract 25 from both sides
25 + N - 25 = 43 - 25
N = 18
