Answer:
the original area is 64ft squared or 169ft squared more perdurable 64
Step-by-step explanation:
(x-2)(x+7)=90
x^2 +5x -14=90
x^2 +5x -14 -90=90-90
x^2 +5x -104=0
factor it out
(x−8)(x+13)=0
so 8 or -13

Answer:
Step-by-step explanation:
Slope Formula: 
Simply plug in your 2 coordinates into the slope formula to find slope <em>m</em>:
If it was 25%, it would be a 90 degree angle. So we can calculate this using a proportion. 25/90 = 24/x. Cross multiply to get 25x = 2160. When you divide by 25 on both sides you get 86.4. So the angle should be 86 degrees. Hope this helps.
