Answer:
Step-by-step explanation:
f(x)=2(x+4)(x-1)
=(2x+8)(x-1)
<h3>=2x²-2x+8x-8</h3>
=2x²+6x-8
Answer:
Step-by-step explanation:
a relation that is not a function
Answer:
N = Q/3 - V
Step-by-step explanation:
Q = 2N + 3V solve for N
Subtract 3V from both sides
Q - 3V = 3N
Divide both sides by 3
(Q - 3V)/3 = N
Q/3 - V = N
or
N = Q/3 - V
Answer: 952 ft squared
Step-by-step explanation:
Surface area, is just the area of all the faces added together.
So, the sides we need to find are measuring:
Triangle side: 10 x 8
Triangle Face; 10 x 8
Square Face: 10 x 10
Square Face: 10 x 10
Rectangular Face: 14 x 10
Rectangular Face: 14 x 10
Bottom Rectangular face: 14 x 10
Side of the Triangular prism: 9 x 14
Side of the Triangular prism: 9 x 14
Because the triangle face has two of them, we only have to do one as opposed to dividing the same face twice.
So, we have a side of 80.
From here, it is just multiplication.
80 + 100 + 100 + 140 + 140 + 140 + 126 + 126 = 952 ft
