<span>Let x = width
2x-3= length

2W + 2L = Perimeter
2(x) + 2(2x-3) = 84
2x+4x-6=84
6x-6=84
6x-6=84+6
6x=90
x=15 ft Width
2x-3 = 2*15-3 = 27 ft Length

Check: 2*15 + 2*27
30 +54
84 It checks!!

I hope this helped!</span>

Simplify. please7−5x−(3+5x) 4 + 10x44−10x10 + 10x

Alenkasestr [34]

Simplify the expression:

7 - 5x - (3 + 5x)

Operate the parentheses. Each term changes its signs because the minus sign represents a -1:

7 - 5x - (3 + 5x) = 7 - 5x - 3 - 5x

Collect like terms:

7 - 5x - (3 + 5x) = 7 - 3 -5x - 5x

Simplify:

7 - 5x - (3 + 5x) = 4 - 10x

Answer: 4 - 10x
