area of playground= 9×15= 135m^2
area of lawn= 3×4=12m^2
total flooring area= 135-12= 123m^2
cost=36×123=$4428
Answer:
C
Step-by-step explanation:
10/3 = 3.33
3.3 = 3.3
pie =3.14
square root of 8 =2.8
M = -1/2
(x₁, y₁) = (-2,-4)
Find the equation
y - y₁ = m(x - x₁)
y - (-4) = -1/2 (x - (-2))
y + 4 = -1/2 (x + 2)
2(y + 4) = -1 (x + 2)
2y + 8 = -x - 2
x + 2y = -10
