(3x - 3)(6x2 - x + 8) add the 3x and -x = 2x
then add -3 + 8 = positive (+) 5
6x2 stays the same due to no like terms
2x + 5 + 6x2 this should be the answer

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

answer: check all that apply, where the options?

step-by-step explanation:

inch

step-by-step explanation:

yard and mile are too big.

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
