3 0
<h3>Answer:  4(x - 1)(x^2 + x + 1)</h3>

==================================================

Work Shown:

4x^3 - 4

4(x^3 - 1)

4(x - 1)(x^2 + x + 1)

In the last step, I used the difference of cubes factoring formula which is

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

One hundred times the quantity five plus three
Maru [420]
Five-5

three-3

"the quantity five plus three" (5 + 3) 

"one hundred times the quantity ..." means  100 (5 + 3)   

now just solve 100(5+3) 

solve the parentheses first (5+3) = 8

Now you are left with 100(8) or 100*8

when you solve your answer is 800

look at the table of x and y (1-3) (2-7) (3-11) which equation is represented by the table a)y=2x+1 B)y=3x+2 C) y=4x-1 D)5x-3
Nostrana [21]
(1,3) , (2,7), and (3,11):
Let's find the slope m between (1,3) and (2,7)
Slope = Rise / Run
m = (7-3) / (1)
m = 4.

Our equation y=mx +b  has a slope of 4. Since C is the only option that satisfies this, we already know the answer, but let's find the y-intercept.
y = mx + b.       Plug in 4 for m, and the first coordinate (1,3) for x and y
3 =4(1) + b       Subtract 4 from both sides
b = -1
Our function is y =4x - 1
Answer is C) y=4x-1
