Answer:

Step-by-step explanation:

Multiply each side by 3.

Answer:
L=6x^2-4x+5
P=12x^2-4x-2
Step-by-step explanation:
A=WL
So, we know the area is 6x^2-8x-30 and the width is 2x-6
Substitute
(6x^2-8x-30)=(2x-6)(L)
L=(6x^2-8x-30)/(2x-6
Divide
L=6x^2-4x+5
P=2L+2W
Substitute
P=2(6x^2-4x+5)+2(2x-6)
P=12×^2-8x+10+4x-12
Simplify
P=12x^2-4x-2
Hints:
Intercepts could mean either x-intercept or y-intercept.
3 zeroes means three x-intercepts.
Answer:
5/6 because 1/2 plus 1/3 is 5/6, meaning that B is the correct answer.
