Kimberly has $13,000 saved for college. Admissions each year is $4,500 college is 4 years. How much money does she still need to save

$5,000

Step-by-step explanation:

4,500*4 is 18,000, and 18,000-13,000= 5,000. If she is going to college for 4 years, then she still needs $5,000

-14 is the answer

hope this : ))

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
