Answer:
7a + 14
Step-by-step explanation:
1. Multiply 7 by a making it 7a.
2. Multiply 7 by 2 making 14.
3. Write the equation as 7a + 14
7a+14 is equal to 7(a+2)
If you use the distributive property and distribute the 7 with both the variable (which is a in this situation) and the constant (2) you get the coefficient of 7a and the constant of 14 like this:
A
x + 9 = 26
x = 17
Answer: g(f(x)) = g(x²-7)=x
-752
16 x 2 x (-24) = -768
-768 + 16 = -752
