Answer:
g(n) = 2n^2 - 4n; Find g(-9)
The answer is 170, because you have to plug in -9 for all the N values. When you do that, just follow PEMDAS.
P-Parentheses
E-Exponents
M-Multiplication
D-Division
A-Addition
S-Subtraction
Step-by-step explanation:
g(-9) = 2(-9)^2 - 4(-9)
g(-9) = 18^2 -4(-9)
g(-9) = 134+36
g(-9) = 170
I really hope this helps!

Answer:
Assuming you're asking for the value of x, the answer would be 4.
Step-by-step explanation:
2(4 + 4)
2(8) = <u>16</u>
4(4) + 3 - 2(4) + 5
4 * 4 = 16
2 * 4 = 8
16 + 3 - 8 + 5
16 + 3 = 19
19 - 8 = 11
11 + 5 = <u>16</u>
16 = 16
