Answer:

<h3>(6x²-11x) is the right answer.</h3>
Helloooo, Your answer for part A is 13 cm
You answer for part b is 2600
13 x 10 x 20 = 2600
C. The vertexes are the same. The functions' vertex (h,k) values were not altered, just a (stretch/compress).
Make the equations equal and solve for x
- 2x²+6x+1=-4x²+1
- 6x²+6x=0
- 6x(x+1)=0
- 6x=0 or x+1=0
- x=0 or x=-1
For x=0
For x=-1
The solutions are
Graph attached
The answer for the question is y = 3x + 5
