Answer:
A) (2x − 7) (4x² + 14x + 49)
C) (3x + 5) (9x² − 15x + 25)
Step-by-step explanation:
Sums and differences of cubes factor as:
a³ + b³ = (a + b) (a² − ab + b²)
a³ − b³ = (a − b) (a² + ab + b²)
8x³ − 343 is a difference of cubes.
(2x)³ − 7³
(2x − 7) (4x² + 14x + 49)
27x³ + 125 is a sum of cubes.
(3x)³ + 5³
(3x + 5) (9x² − 15x + 25)

Answer:
y = -x +3
m = -1
b = 3
Step-by-step explanation:
To solve the given equation for y, divide by the coefficient of y.
(-3y)/(-3) = (3x -9)/(-3)
y = -x +3
__
The slope is the x-coefficient, M = -1.
__
The y-intercept is the added constant, B = 3.
__
Both equations are graphed in the attachment. Texture has been added to the original so you can see the graphs are the same line.
Answer:
5.2
Step-by-step explanation:
g(x) = mx +b
g'(x) = m = 2 for all x
g(-1) = 2(-1) + b = 5
-2 + b = 5
b = 7
So, g(x) = 2x + 7
Therefore g(-.9) = 2(-.9) + 7
= -1.8 + 7 = 5.2
What do they call the international hula hoop championships??
The Whirl Series!
75 feet wide and 105 feet long.
You multiply the scale factor by rbe actual length of the sides. So 5 time 15 because there are 5 inches and each one is worth 15 feet. And 7 time times 15 because of the same reason
