Pls help you dont have to explain just answer

Problem 1:  g(x) = (x - 3)(x + 18)

Problem 2:  Option A, y = 1.2x - 6

Problem 3:  Option D

Step-by-step explanation:

Problem 1:

g(x) = x^2 + 15x - 54

g(x) = (x - 3)(x + 18)

 Option B, g(x) = (x - 3)(x + 18)

Problem 2:

Slope = 1.2

(y - y1) = m (x - x1)

(y - 0) = 1.2(x - 5)

y = 1.2x - 6

 Option A, y = 1.2x - 6

Problem 3:

 Option D

Look at attached graph:  

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
