Answer:
![\large\boxed{5x^2+6x-8=(x+2)(5x-4)}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B5x%5E2%2B6x-8%3D%28x%2B2%29%285x-4%29%7D)
Step-by-step explanation:
![5x^2+6x-8\\\\=5x^2+10x-4x+8\\\\=5x(x+2)-4(x+2)\\\\=(x+2)(5x-4)](https://tex.z-dn.net/?f=5x%5E2%2B6x-8%5C%5C%5C%5C%3D5x%5E2%2B10x-4x%2B8%5C%5C%5C%5C%3D5x%28x%2B2%29-4%28x%2B2%29%5C%5C%5C%5C%3D%28x%2B2%29%285x-4%29)
Answer:
The answer is 84° because they are the same thing just on opposite sides therefore they would be the same thing.
I don't know if its a right triangle and we are trying to find the length of the hypotenuse
but if it is, use Pythagorean Theory
c² = √a² + b²
c² = √12² + 5²
c² = √144 + 25
c² = √169
c=13
It would help to know the equation... but I’m pretty sure it would be
C (times amount)=P, sooo
(C)A=P
Replace the A with amount from previous questions, take away the parentheses, and your golden. Hope that helped!
