length of pool, L = 10 + W
width of pool, W
pool area = W(10+W)
backyard is square shaped.. sides are equal
backyard side length, S = 5 + 3W
Area backyard = (5+3W)(5+3W)
subtract pool area
Area surrounding pool
= (5+3W)(5+3W) - W(10+W)
simplify the expression, foil
= 25 + 30W + 9W^2 - 10W - W^2
combine like terms
A = 8W^2 + 20W + 25
To solve the function we proceed as follows:
5c+4=2(c-5)
opening the parentheses we get:
5c+4=2c-10
putting like terms together we get
5c-2c=-10-4
3c=-14
c=-14/3
