The area a of a rectangle parking lot is given by the equation a=16s^2+25. jacob knows the area of the parking lot and wants to find s. solve a=16s^2+25 for s

s = sqrt(A - 25)/4

Step-by-step explanation:

A = 16s^2 + 25

Switch sides.

16s^2 + 25 = A

Subtract 25 from both sides.

16s^2 = A - 25

Divide both sides by 16

s^2 = (A - 25)/16

Take the square root of each side.

s = sqrt[(A - 25)/16]

s = sqrt(A - 25)/4

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
