Would you solve the equation 10=4(y-1) by using distributive property

Yes, it would look like the following:

10 = 4(y-1)

10 = 4y - 4

10 + 4 = 4y

14 = 4y

14/4 = 4y/4

3.5 = y

I hope this is right, and what you're looking for.

answer: #1 ads up by 8 and i don't know #2

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
