Solution:
f(x) = 2x + 3
g(x) = x - 9
f(x) + g(x)
= (2x + 3) + (x - 9)
= 2x + x + 3 - 9
= 3x - 6
Answer:
A=a+b
2h=20+8
2·20.4≈285.6
Step-by-step explanation:
A. Your Choice
B. Green (Your Choice, but the other answers are only applicable if you use 1 color.)
C. Same color
D. The walls are 8 * 20 ft and 8 * 25 ft, and there are 2 of each of those.
That means you are painting 720 ft^2
There is 1 gallon per 400 ft^2, so you need 2 gallons of paint.
It costs $13.98 per gallon, so you need $13.98 * 2 = $27.96
