Answer:
2x^2 - 16x + 30
Step-by-step explanation:
Here, we want to get the composite function;
p•q(x)
All we have to do here is to replace the x value in p(x) by the totality of q(x)
we have this as ;
= 2(x-3)^2 - 4(x-3)
= 2(x^2 -6x + 9) - 4(x-3)
= 2x^2 -12x + 18 -4x + 12
= 2x^2 - 16x + 30
Answer:
22
Step-by-step explanation:
The problem can be solved geometrically. By this way, the solution is going to be easy, as well.
We can see from the attached graph that the coordinates are the vertexes.
Considering a unit distance, we can find that the width of this rectangle is:
4 = 12 - 8
and the length is:
7 = 6-(-1)
Then, the perimeter is P = (4+7)*2 = 22

Step-by-step explanation:

I am joyous to assist you at any time.
I would think it would be all real non zero numbers. I mean if x is time you can't have negative time, right?
