Answer:
2x - 3
Step-by-step explanation:
The are of a rectangle is computed using the formula:
A = L x W
The area given is:
2x² + 5x -12
So:
2x² + 5x -12 = L x (x + 4)
So we can solve this through division:
<u> 2x - 3 </u>
x + 4 | 2x² + 5x - 12
<u> - 2x² + 8x </u>
-3x - 12
<u>- -3x - 12</u>

Answer:
7 shirts
Step-by-step explanation:
You first have to subtract 22 from 80, since that's how much she already spent, 80-22=58. Now you have to do 58/8, but since 8 doesn't divide evenly into 58, you have to go with the closet multiple of 8 which would be 56. 7x8=56, so Jenna can buy a maximum number of 7 shirts.
The best way to work this problem
would be to find the height of the triangle. I would use the trig function “sin” to find the height. You would then plug the height in to the function to get the base (x or y). After you have the height and base use the “sin” function again to find the other side (variable).
