) is represented by the following formula:

Where:
- Width.
- Length.
If length is increased by 120 %and width is decreased by 20 %, the percentage change in the area of the rectangle is: (
,
)



The area of the rectangle is increased in 76 percent.
The parabola is going downwards.
The equation for the axis of symmetry is x = -1.
The vertex is at -1,9
The x-intercepts are at -4, 2
Answer:20/8/15= 0.16666666666
Answer:
2622
Step-by-step explanation:
Basically, whenever you see a x you insert a 6 into the original equation (since x=6).
2x^4+5x --> 2(6)^4+5(6)
6^4=1296
so 2(1296)+30=2622
