Answer:

3x(2x^2 +x-1)

Step-by-step explanation:

f(x) = 11x^3 + 3x^2 - 4x + 2,

g(x) = 5x^3 - 7x + 2,

f(x) - g(x) =11x^3+3x^2-4x+2 - (5x^3-7x + 2)=

11x^3+3x^2 -4x+2-5x^3+7x-2=

(11x^3-5x^3)+3x^2+(-4x+7x)+(2-2)=

6x^3 +3x^2 - 3x=

3x(2x^2 +x-1)

What is the ratio of quarters to nickels in a dollar

sleet_krkn [62]

For quarters we have:

$0.25x = 1$

Where,

x: number of quarters

Clearing x we have:

$x = \frac{1}{0.25}\\x = 4$

For nickels we have:

$0.05y = 1$

Where,

y: number of nickels

Clearing y we have:

$y = \frac{1}{0.05}\\y = 20$

Then, the ratio of quarters to nickels is:

$\frac{x}{y}= \frac{4}{20}$

Simplifying we have:

$\frac{x}{y} = \frac{1}{5}$

Answer:

The ratio of quarters to nickels in a dollar is:

$\frac{x}{y}= \frac{1}{5}$

A spinner has 12 equal sections:5 red 4 green and the rest are black. In 921 spins how many times can you expect to spin black?

Komok [63]

Answer:

230

Step-by-step explanation:

12 sections total

5 red, 4 green, the rest black

12-5-4 = 3 sections are black

3/12 = 1/4 of the sections are black

1/4 represents the probability of landing on black for one spin

(1/4)*921 = 230.25 which rounds to 230

We expect to land on a black section about 230 times out of 921 times total.
