Answer:
247
49
Step-by-step explanation:
a) f•g (4) =
f•g (x) = f(g(x)) = (x + 9)^2 + 6(x + 9)
f•g (4) = (4 + 9)^2 + 6(4 + 9)
= 13^2 + 6(13)
= 247
B) g•f (4) =
g•f (x) = g(f(x)) = x^2 + 6x + 9
g•f (4) = 4^2 + 6(4) + 9
= 16 + 24 + 9
= 49
B at most 3 times
2 3/4 - 1 1/4 = 1 1/2
1 1/2 ÷ 1/2 = 3
used 1/2 ounce 3 times
so I'd say the answer is b at most 3 times because he couldn't have used it more than 3 times

Answer:
<h2>1.76pints of blue paint</h2>
Step-by-step explanation:
The total number of paint used = 8.8pints
If 4/5 of this amount is white paint, then the amount of white pint is expressed as;
= 7.04
This means the amount of white paint used is 7.04pints.
amount of blue paint used = Total amount of paint - amount of white paint
amount of blue white paint used = 8.8 - 7.04
amount of blue paint used = 1.76pints of paint
