Answer:
-9
Step-by-step explanation:
Substitute 3 for <em>z</em><em> </em>and 9 for <em>w</em> in the equation.





1/4 foot = 3 inches.
The area of a 1/4-ft square is (3" x 3") = 9 square inches.
1/3 foot = 4 inches.
The area of a 1/3-ft square is (4" x 4") = 16 square inches.
The 1/3-ft square tile covers more area than a 1/4-ft square tile
covers. So she won't need as many 1/3-ft tiles to cover the floor
in her room. She will use fewer of those.
1. Add 5 to both sides. So x=5. That is a vertical line. The answer is undefined
2. 25- 5 7/8 + 6 1/2
Denominators have to be the same
Multiply 1/2 by 4/4
25-5 7/8 + 6 4/8
25 - 11 11/8
23 16/8- 11 11/8
12 5/8
We first need to find f(3).
f(3) = 2(3) + 8
f(3) = 6 + 8
f(3) = 14
We now want g(f(3)).
We know that f(3) is 14.
We also know that g(x) is 5.
As you know, 5 is a constant. No matter what the value of x is for g(x), it will not change the value of g(x).
So, g(f(3)) = g(14) = 5.
Answer: g(f(3)) = 5.
