Answer:

Step-by-step explanation:

Using perimeter =2(l+b)

74=2(L+B)

From the question

Width(b)=x & length(l)=3x+5

So we have that

74 =2(3x+5+x)

Adding like terms we then have that

74 =2(4x+5)

Opening the bracket gives

74=8x +10

Collecting like terms

8x=74-10

8x= 64

Therefore

X=64/8

X=8feets

The width is 8feets

mylen [45]

10x = 4(2x -9)

10x - 8x = -36 - 8x

2x = -36

2x ÷ 2 = -36 ÷ 2

x = -18
