What are the zeros of f(x)= x^2+x-30

a. x=-5 and x=6
b. x=-2 and x=15
c. x=-6 and x=5
d. x=-15 and x=2

C

Step-by-step explanation:

The zeros of the function is the roots and solutions. To find them, factor the equation into two binomials.

To solve, set each binomial to 0 and solve for x.

x+6 = 0

x = -6

x-5=0

x=5

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
