The side lengths of a triangle are given by the expressions 5x+3,5x+5,and3x-2.write and simplify a linear expression for the per

serg [7]

The perimeter of the triangle is: 13x+6

Step-by-step explanation:

The perimeter is the length of the outer boundary of any closed geometrical shape.

So,

Given

$Side\ 1 = s_1 = 5x+3\\Side\ 2 = s_2 = 5x+5\\Side\ 3 = s_3 = 3x-2$

The perimeter will be:

$P = s_1+s_2+s_3\\= (5x+3)+(5x+5)+(3x-2)\\=5x+5x+3x+3+5-2\\=13x+6$

The perimeter of the triangle is: 13x+6

how many different combinations of six people can sit in four chairs? assume one person sits in each chair

Tems11 [23]

We want to choose 4 people and we have 6 people to choose from. This is a combination of 6, 4 by 4. Also called six choose four.

The following formula:

$_rC_n=\frac{n!}{r!(n-r)!}$

Is the combination of $r$ objects choosen from a total of $n$ . It's $n$ choose $r$ .

For our problem, we just need to compute the following:

$_4C_6=\frac{6!}{4!(6-4)!}=\frac{6\times5\times4!}{4!2!} =\frac{6\times5}{2\times1} =15$

Thus

$\boxed{_4C_6=15}$

Therefore the answer is 15 different combinations
