Answer:
10+4x
Step-by-step explanation:
COmbine like terms
Length (L): 2w + 6
width (w): w
Perimeter (P) = 2L + 2w
240 = 2(2w + 6) + 2(w)
240 = 4w + 12 + 2w
240 = 6w + 12
228 = 6w
38 = w
Length (L): 2w + 6 = 2(38) + 6 = 76 + 6 = 82
Answer: width = 38 ft, length = 82 ft

Answer:
Step-by-step explanation:
m³ -216 = m³ - 6³
a³ - b³ = (a-b) (a² + ab + b²)
a = m and b = 6
m³ - 6³ = (m - 6)(m² + 6m + 6²)
= (m - 6)(m² + 6m + 36)
