The area of a rectangular wall of a barn is 153 square feet. Its length is 8 feet longer than the width. Find the length and width of the wall of the barn.

Answer and Step-by-step explanation:

Area (A) = 153

Length (l) = 8 + w

Width (w) = w

A = lw

153 = (8 + w)(w)

153 =

0 =   - 153

(w - 9)(w + 17)

w = 9

w = -17

We can't have a negative length, so we only use 9.

w equals 9.

That means l equals 17     (9 + 8 = 17).

Length = 17

Width = 9

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
