You give up a full-time salary of $45,000 a year to go to school for 2 years. the total cost of going to school is $30,000. if you want to be able to recover your investments in 5 years or less, what is the minimum salary you would need to earn upon earning your degree

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

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
