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

step-by-step explanation:

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
