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: 26
Step-by-step explanation:
Area of a rectangle is length times width.
The area, 42, divided by the length, 7, is 6.
2 sides of the rectangle are 7, so the other 2 are 6.
6+6+7+7=26. The perimeter is 26.
Answer:
Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi
Step-by-step explanation:
The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.
When x = 0
A. 0, 7 is your answer
