Step 4:2 (1) = 12(2)

Step 5: c = 24

c = 24

Step-by-step explanation:

The given equation is :

Adding both sides by 5 both sides,

Cross multiplying both sides,

c = 24

So, the value of c is 24.

i believe that the answer is

b. y-1=-2(x-4)

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
