Determine the width of the garden. nina must put 60 feet of fencing around her rectangular garden. the length of the garden is three feet longer than twice the width. what is the solution set for 2w + 2(2w + 3) = 60 given the replacement set {6, 7, 8, 9}?

2w+2(2w+3)=60

2w+4w+6=60

6w+6=60

6w=54

w=54/6 =9

 the width is 9 feet

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
