Aleksandr-060686 [28]

Answer:

$Students = \frac{1}{50}$

Step-by-step explanation:

Given

$Track = \frac{1}{30}$

$Pizza = \frac{3}{5}$

Required

The fraction of students in the school that ate Pizza

To do this, we simply multiply the fraction of track students and those among them that ordered pizza.

So, we have:

$Students = Pizza * Track$

$Students = \frac{3}{5} * \frac{1}{30}$

$Students = \frac{1}{5} * \frac{1}{10}$

$Students = \frac{1}{50}$

Simplify. <br><br> −3x3(−2x2+4x−3)

stepladder [879]

Answer:

$-3x^3(-2x^2+4x-3)$ simplifies to $6x^5-12x^4+9x^3$

Step-by-step explanation:

Given expression $-3x^3(-2x^2+4x-3)$

We have to simplify the above expression,

Consider the given expression $-3x^3(-2x^2+4x-3)$

Multiply each term in brackets by $-3x^3$ , we get,

$-3x^3(-2x^2+4x-3)=-3x^3(-2x^2)-3x^3(4x)[-3x^3(-3)$

Solving further, using $x^n\cdot x^m=x^{n+m}$ we get,

$-3x^3(-2x^2)-3x^3(4x)[-3x^3(-3)=6x^5-12x^4+9x^3$

Thus, $-3x^3(-2x^2+4x-3)$ simplifies to $6x^5-12x^4+9x^3$
