Factor completely 3x^4 - 3x ^3 - 18x ^2. Which of the following is one of the factors?

Otrada [13]

Answer:

$3x^4 - 3x ^3 - 18x ^2=3x^2(x+2)(x-3).$

Step-by-step explanation:

The expression $3x^4 - 3x ^3 - 18x ^2$ consists of three terms:

$3x^4;$
$-3x^3;$
$-18x^2.$

These three terms have common factor $3x^2.$ Thus,

$3x^4 - 3x ^3 - 18x ^2=3x^2(x^2-x-6).$

Consider the expression $x^2-x-6.$ You can rewrite it as

$x^2-x-6=x^2+2x-3x-6=x(x+2)-3(x+2)=(x+2)(x-3).$

The whole expression takes look

$3x^4 - 3x ^3 - 18x ^2=3x^2(x+2)(x-3).$

Answer:

10% of 50 coins is/are 5 coins. So, 5 coins are pennies.

40% of 50 coins is/are 20 coins. So, 20 coins are dimes.

The number of nickels is (5 + 9) = 14, according to the condition.

Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.

Now you can easily calculate the total and answer the question

Total = 5*1 + 14*5 + 20*10 + 11*25 = 550 cents = $5.50. ANSWER
