Answer: C. x+9</h3>
===============================================
Explanation:
Think of two numbers that multiply to -36 and also add to 5. Put another way: think of two factors of -36 that add to 5.
Those two numbers are 9 and -4 since
9 times -4 = -36
9 plus -4 = 5
So we have x^2 + 5x - 36 factor into (x+9)(x-4)
x+9 is one factor
x-4 is the other factor

Alternatively, you can use a graphing tool to locate the x intercepts, and that will in turn lead to the factorization. Or you could use the quadratic formula to get the job done. Completing the square is yet another tool to use. So there are multiple approaches.

Answer: C, I think!
Step-by-step explanation: 3pi equals 9.4247. The square root of 100, is 10. So, that gives us 10/4. That simplified gives us 2.5.
For A, the square root of 36 is 6. 6 is in between 2.5 and pi, so that is not it.
For B, pi to the second power over 3 equals 3.2897, so that’s not it too!
For C, pi over 2 is 1.5708, so that is it, I’m pretty sure!
