Meg's teacher asked her to find the zero(s) of the equation below.  Meg decided to factor to find the zero(s). 
0= x²-4x +4

(x + ___) (x + ___)

• (x + -2)(x + 2)

• (x + -4)(x + 2)

• (x + -4)(x + 4)

• (x + -2)(x + -2)

Emily makes $10 per hour at her job.  Her paycheck was $370.  If h represented the number of hours Emily worked, which equation below represents Emily's paycheck?

• h =10/370

• 370h = 10

• 370 (10) = h

• 10h = 370
