9. Use the hints to write the 5 - 4(x - 3) = -15
2.5x + 1 - 7x = -44
2/4x – 12) + 1 = 9
• Rob, Maddie and Belinda each solved an equation.
The solution to Maddie's equation is twice the solution to Rob's equation.
The solution to Belinda's equation is 2 more than the solution to Maddie's equation.

i wish i could you, i have no idea how to answer this

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

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
