Can someone help me solve for x & explain how they got it please?? i have a test tomorrow!!

36=x^2+5x

x^2+5x-36=0

(x+9)(x-4)

x= 4

x= -9

The Answer can be 4 or -9, see which option you have.

Step-by-step explanation:

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
