Find (x + 7x2 - 167–112) /
(x+4) by using synthetic division:

x² + 3x  - 28

Step-by-step explanation:

Division of the polynomial by (x + 4), evaluate at h = - 4

- 4 | 1   7   - 16   - 112

          - 4   - 12     112

      1     3     - 28    0 ← remainder = 0

quotient is x² + 3x - 28

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

a is the right answer
