3y to the power of two + 14y

23y

Step-by-step explanation:

3y² + 14y

9y + 14y

23y

(3y+2)(y+4)

Step-by-step explanation:

3y^2 +14y

This question would factor to:

(3y+2)(y+4)

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

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
