The correct answer is C. (5x+3) feet, and here is how I got it.
This is the equation you need to use:
(a+b)^2 = (a+b) (a+b)
So, let us plug in 5x and 3 here:
(5x+3)^2 = (5x+3)(5x+3) = 25x^2 + 15x + 15x + 9 = 25x^2 + 30x + 9 which is the area of the garden.

Answer:
N = Q/3 - V
Step-by-step explanation:
Q = 2N + 3V solve for N
Subtract 3V from both sides
Q - 3V = 3N
Divide both sides by 3
(Q - 3V)/3 = N
Q/3 - V = N
or
N = Q/3 - V
