Sam makes $7.50 per hour at work, and he works anywhere from 15 - 40hrs per week. Occasionally the store gets really busy, and Sam's boss allows him to work up to 15hrs of overtime. Sam loves the busy weeks, because he makes "time-and-a-half", or $11.25, for overtime hours.

the answer is b.

step-by-step explanation:

x=0

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
