How many solutions does the equation 9x +3=9x + 5 have?

This equation doesn't have any solution

Step-by-step explanation:

Given that,

9x +3=9x + 5

Subtract 3 from both sides

9x+3-3=9x+5-3

9x=9x+2

Since 9x cannot be equals to 9x+2, no matter the value of x.

Or further still divide through by 9

9x/9 = 9x/9 + 2/9

x=x + 2/9

it is not possible for x to be equal to x+2/9.

So it doesn't have a solution

x≠x+2/9

i dont understand the question? ?

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
