I say D because sum is the total when you add and when it says less you go backwards ex.2 less than 3 this is how you write it 3-2
Let width be “w", length = “l" and perimeter = p
Then l = 3w-4
Perimeter = 2(w+l)
p = 2(w+3w-4) = 2w+6w-8 = 8w-8
Perimeter is 32…
8w-8 = 32
8w = 32+8
8w = 40
w = 5
l = (3×5)-4 = 11
Check… p = 2(5+11) = 2 × 16 = 32
Ans = length is 11
Hope it helps!
2/3 two over three I’m pretty sure I’m good at this stuff hope I helped.
Part A: a percent decrease
part B: 12.5 percent decrease
