Answer:

$15x^3 +10x^2 - 15x$

Step-by-step explanation:

Hello!

Use the distributive property and multiply like terms.

<h3>Simplify</h3>

$5x(3x^2 + 3x - 3)$
$5x(3x^2) + 5x(2x) + 5x(-3)$
$15x^3 +10x^2 - 15x$

The simplified form is $15x^3 +10x^2 - 15x$ .

Name the solid and find its volume. Use 3.14 as the approximate value of pi.

sineoko [7]

It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .

The formula of volume of cone is

$V = \frac{1}{3} \pi r^2 h$

To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is

$V = \frac{1}{3} *3.14*7^2 *16 = 820.6 \ units \ cube$

And that's the required volume of the cone .

Solve 2(x-3)>-3(-3+x) (Picture added, multiple choice)

Rudiy27

Answer:

Answer: D

Step-by-step explanation:

$2(x - 3) \geqslant - 3( - 3 + x)$

open the brackets [ distributive property ]

$2x - 6 \geqslant 9 - 3x$

collect like terms:

$2x + 3x \geqslant 9 + 6 \\ 5x \geqslant 15$

divide either sides by 5:

$\frac{5x}{5} \geqslant \frac{15}{5} \\ \\ { \underline{ \bf{ \: \: x \geqslant 3 \: \: }}}$
