The answer to your questions is 11 because PEMDAS. () exponents multipication division addition and subtraction.
By substitution.
Get y or x alone then insert it into the other equation solving for one of the two variables. After that substitute ur answer into one of the equations then solve.
Formula
Volume = A_base * height
Solution
Synthetic Division always changes signs of the divisor. Also you add whereas in long division you subtract.
-2 || 2 + 9 - 8 - 36
-4 -10 36
===================
2 5 -18 0
You can eliminate A and B. You are never left with the same power at the beginning when you do a division.
What you are left with is
A_Base = 2x^2 + 5x - 18

Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The x- coordinate of the vertex is at the midpoint of the zeros.
Given
f(x) = (x - 4)(x + 2)
Find the zeros by letting f(x) = 0 , that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 4 = 0 ⇒ x = 4
Then
=
=
= 1
Substitute x = 1 into f(x) for corresponding y- coordinate
f(1) = (1 - 4)(1 + 2) = (- 3)(3) = - 9
Vertex = (1, - 9 )
