Amber, Bernie, and Carlos are working on a problem together. Their goal is to correctly apply the difference of cubes formula to
NeX [460]

Answer: Carlos is correct

Step-by-step explanation:

2x^5-250x^2

The first step is to factorize out 2x^2

2x^2(x^3-125)

This can be rewritten as

2x^2(x^3-5^3),

Recall, difference if cube (a^3-b^3)

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

from our equation,

a= x

b = 5.

So the difference of cubes will be

2x^2[(x-5) (x^2 + 5x + 5^2)]

=2x^2[(x-5) (x^2 + 5x + 25)]

Carlos followed these steps. So he is correct. Carlos is correct because he correctly factored the GCF, identified a and b, and applied the difference of cubes method.

Amber is incorrect because 125 is equal to b3, not b.

Bernie is incorrect because x2 is not the GCF of the polynomial. The GCF is 2x^2.

Help asap Which explains how to find the quotient of the division below? -3 1/3 divided by 4/9
noname [10]

Answer:

-7\frac{1}{2}

Step-by-step explanation:

To find the quotient, convert the mixed number to an improper fraction first

-3\frac{1}{3}=-\frac{3*3+1}{3}=-\frac{10}{3}

Find the quotient now

\frac{(-10/3)}{(4/9)}=-\frac{10*9}{4*3}\\ \\=-\frac{90}{12}

Simplify

Divide by 6 both numerator and denominator

=-\frac{15}{2}=-7.5

Convert to a mixed number

-7.5=-(7+0.5)=-(7+\frac{1}{2})=-7 \frac{1}{2}
