Answer:

8.5-5.7n-4b

Step-by-step explanation:

Variable- x, y, or in your case n and b

1. You can't subtract or add numbers with a different variable. For example you can't do 4b-3a so you can't so 5.7n-4b.

2. If there are numbers without variables do them first. 2.5+6=8.5

3. Now since you can't subtract those numbers with variables you right your final equation. Start with your answer that replaces 2.5- 8.5 Then you see put down- 5.7n- 8.5-5.7n Then lastly you have- 4b- 8.5-5.7n-4b

L +2w = 500
a = lw

a) l = 500 -2w
.. a = (500 -2w)*w

b) The zeros of the above equation are w=0, w=250. The vertex of this quadratic is on the line of symmetry, halftway between the zeros, at w=125 ft.

c) a = (500 -2*125)*125 = 31,250 . . . . square feet
