Which are solutions of the equation (x + 5)(x - 3) = 0? check all that apply.
ox=-15
ox = -5
ox = -3
ох= 2
ox = 3
ox = 5

-5 and 3

Step-by-step explanation:

Simply set x+5 equal to zero.

Set x-3 equal to zero.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
