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

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

A storage locker measures 5 feet by 6 feet by

Snezhnost [94]

Answer:

$420 \: {feet}^{3}$

Step-by-step explanation:

Space occupied by storage locker in the warehouse will be equal to its volume.

$\therefore \: volume \: of \: storage \: locker \\ = 5 \times 6 \times 14 \\ = 30 \times 14 \\ = 420 \: {feet}^{3}$

Hence, storage locker will occupy 420 cubic feet of space in the warehouse.

What is x in the similar triangles? Please help:)

topjm [15]

Answer:

x = 18

Step-by-step explanation:

Since both right triangles are similar, therefore:

$\frac{2x - 6}{20} = \frac{39}{x + 8}$

Cross multiply

$(2x - 6)(x + 8) = 39*20$

$2x(x + 8) -6(x + 8) = 780$

$2x^2 + 16x - 6x - 48 = 780$

$2x^2 + 10x - 48 = 780$

Subtract 780 from both sides

$2x^2 + 10x - 48 - 780 = 0$

$2x^2 + 10x - 828 = 0$

$2x^2 + 46x - 36x - 828 = 0$

$2x(x + 23) - 36(x + 23) = 0$

$(x + 23)(2x - 36) = 0$

x + 23 = 0

x = -23

2x - 36 = 0

2x = 36

x = 18

$120; Markup: 35%<br><br>What's the final price? pls show how u got the answer...

Tju [1.3M]

Answer: 162

Step-by-step explanation:

So you will need to find the Markup. The original cost is $120.

Divide the number by 100 is 1.2. $1.2 is 1% of the $120.
Now times the number by 35. $1.2 x 35 is $42.
Finally, add the number. 120 + 42 = 162.

I hope this is the answer you are looking for.
