It's useful to divide out the GCF first because it makes factoring easier as the coefficients are smaller requiring less steps. 

Example where you don't factor GCF first...
4*-32 = -128
numerous factor pairs for 128 ... takes time to find the correct one
right factor pair is 16,-8
substitute for 8x
4x² + 16x - 8x - 32 = 0
group then factor
4x(x+4) - 8(x+4) = 0
group again
(4x-8)(x+4) = 0

Example of factoring GCF first
4x² + 8x - 32 = 0
4 is GCF
x² + 2x - 8 = 0
factor
(x+4)(x-2) = 0

Solving for x gives the same answer just less steps and simpler math when you factor GCF first.

Alex

Answer:

How much will a 60 affect my grade?

If it is a test grade, which in my school they are worth 60%, then it will bring you down by pretty much a whole lot, probably about 7–10 points. If it is a 20% weight it will only bring it down by about 2–3 points.

Find the area of the figure. round your answer to the nearest hundredth
liraira [26]

Answer: 84.14

Step-by-step explanation:

Area of the rectangle is L*W=B*H

14*5=70

To find the area of the half circle we must use the formula pi r^2/2

r=radius

and the radius is 6 because we add 4 and 4 and need to get to 14

because the line below it is 14 and it is a rectangle so the lengths are the same.

Diameter=6

So radius =3

pi (3)^2/2=

9/2 pi + 70=

Stells [14]

Answer:

(1)raise, (2)decrease

Step-by-step explanation:

A monopolist's marginal cost curve shifts up, but the firm's demand curve remains the same and the firm does not shut down. Compared with the condition before the increase in marginal costs, the monopolist will <u>raise</u> its price and <u>decrease</u> its level of production.

Marginal cost is the additional cost incurred when one more unit of the output is produced. It is a J-shaped curve, which <em>initially decreases, reaches its minimum and then starts increasing.</em>

Marginal cost is an important factor in economic theory because a company that is looking to maximize its profits will produce up to the point where <em>marginal cost (MC) equals marginal revenue</em>
