Question

Write an inequality for x that would give this rectangle an area of at least 300ft sq2
the numbers are X+5ft 3ft

Answer 1

Answer:

Step-by-step explanation:

P≥300

300≤P

P=2(L+W)

300≤2(L+W)

L=3

W=x+5

300≤2(3+x+5)

300≤2(8+x)

divide both sides by 2

150≤8+x

minus 8 both sides

142≤x

x is at least 142

width is at least 147
