Ihave one more for now. : ) solve 8x² - 10x - 52= 0

Let's solve your equation step-by-step.

8x2−10x−52=0

Factor left side of equation.

2(4x−13)(x+2)=0

Set factors equal to 0.

4x−13=0 or x+2=0

x=13/4 or x=−2

maybe it's 54x=52 might be if this is wrong, my bad.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
