let's solve for x ~

$- 8x + 4 < 36$

$- 8x < 36 - 4$

$- 8x < 32$

$- x < 32 \div 8$

A bag contains 9 tiles, each with a different number from 1 to 9. You choose a tile without looking, put it aside, choose a seco

Ksenya-84 [330]

Using the combination formula, it is found that there are 84 ways to choose the three tiles.

The order in which the tiles are chosen is not important, hence the <em>combination formula</em> is used to solve this question.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem, three tiles are chosen from a set of nine, hence:

$C_{9,3} = \frac{9!}{3!6!} = 84$

There are 84 ways to choose the three tiles.

Subtract the polynomials then simplify: 5x^5+4x^2-2x^6+6x^4 and 10x^2+10x^3+8x^6-9x^4

Jet001 [13]

Answer:

$\large\boxed{-10x^6+5x^5+15x^4-10x^3-6x^2}$

Step-by-step explanation:

$(5x^5+4x^2-2x^6+6x^4)-(10x^2+10x^3+8x^6-9x^4)\\\\=5x^5+4x^2-2x^6+6x^4-10x^2-10x^3-8x^6-(-9x^4)\\\\=5x^5+4x^2-2x^6+6x^4-10x^2-10x^3-8x^6+9x^4\\\\\text{combine like terms}\\\\=(-2x^6-8x^6)+5x^5+(6x^4+9x^4)-10x^3+(4x^2-10x^2)\\\\=-10x^6+5x^5+15x^4-10x^3-6x^2$
