Answer:
![-6(x^2+3x+4)](https://tex.z-dn.net/?f=-6%28x%5E2%2B3x%2B4%29)
Explanations:
The given expression is
![-6x^2-18x-24](https://tex.z-dn.net/?f=-6x%5E2-18x-24)
This can be factored as shown below:
1) Get rid of the square. You have to square root both sides.
2) Subtract 7 from both sides.
3) x= -1
The answer is B, (plus 5)
Answer:
What angle should a ramp be?
Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree angle; 12.5% grade). Minimum width should be 36" (inside rails) - (48" is ideal)

30% , as:
Let the percentage of people preferring wooden skateboards be 'x'.
Therefore, x/100*643=209
x/100=209/643
x=209*100/643
x=20900/643
x=32.50.......
By rounding it off to 30, we get 30% as answer.
