Answer:

Step-by-step explanation:

Factor 6f3−8f2+20−15f

6f^3−8f^3−15f

=(3f−4)(2f2−5)

Answer:

(3f−4)(2f^2−5)

Find the group you want to factor, such as in the first parenthesis, you remove 3f from the whole equation, and end up with 3f-4. You take the end value, and group it with -5. You will then end up with 2f^2 -5.

Hope this Helps!

A sofa is on sale for $219, which is 27% less than the regular price. What is the regular price?

Tems11 [23]

Answer:

$300 was the regular price of the sofa.

Step-by-step explanation:

If $219 is 27% less than the regular price, then it represents 73% of the regular price.

Regular price = r.

r/1 x 73/100 = $219. Reverse this to find that $219/1 divided by 73/100 = r.

To divide fractions, reverse the second fraction and MULTIPLY:

$219/1 x 100/73 = 21900/73 = 300.

(w-10x) (w+10x) Use the Identities to solve this question

Inessa [10]

We are provided that –

(w-10x) (w+10x)

Applying identity –

a² - b² = (a + b)(a - b)

$\qquad$ $\twoheadrightarrow\bf(w-10x) (w+10x)$

$\qquad$ $\twoheadrightarrow\bf w^2 - (10x)^2$

$\qquad$ $\twoheadrightarrow\bf w^2 -100 x^2$
