1. Find the GCF of 6x2+66x+30. 2. Factor completely 4x3-12x2-5x+15.
3. Factor completely 4x2 - 25.
4. Factor completely 9x2+66x+21.
5. Factor completely 63x3+54x2-28x-24.
6. The area of a rectangle of (x2-144)square units. Determine the dimensions of the rectangle by factoring completely.
7. Identify the key features of the function and graph the function. f(x) = x2 -5x+6
8. Work backwards, using the Distributive Property, to check the factors and identify the original polynomial of this factored function: (2x+5y)(x+7y)

the answer is here: : )

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
