65% of 89
65/100 = .65

Answer: 57.85
The answer is 3.
$6 x 6 = 36
45 - 36 = 9
9 divided by 3 = 3 burgers
I cant see your work very clearly so I'll work it out below:-
f(x + Δx) = (x + Δx)^2 - 2(x + Δx) - 3
= x^2 + 2x(Δx) + (Δx)^2 - 2x - 2(Δx) - 3
= x^2 - 2x + (Δx)^2 + 2x(Δx) - 2(Δx) - 3
Perimeter = 2l+2w in this case. So 16+12, 28 feet is your answer!
