We want to know the perimeter and area of a rectangle given that we know where the vertices are.

We will get:

perimeter = 26

area = 42

While you wrote verticals, you wrote points, then I assume that it should say vertices.

The vertices of the rectangle are:

(-3.5, 3), (3.5, 3), (-3.5, -3), and one missing but that is the final one, (3.5, -3).

Note that we have two x-values and two y-values, we can define the length as the difference in the x-values and the width as the difference in the y-values, then we will get:

length = 3.5 - (-3.5) = 7

width = 3 - (-3)  = 6

Now we know the length and width of the rectangle, the perimeter is:

P = 2*(6 + 7) = 26

The area is:

A = 6*7 = 42

allsm [11]

Answer:

16/15

Step-by-step explanation:

Simplify the following:

8/3 - 8/5

Put 8/3 - 8/5 over the common denominator 15. 8/3 - 8/5 = (5×8)/15 + (3 (-8))/15:

(5×8)/15 + (3 (-8))/15

5×8 = 40:

40/15 + (3 (-8))/15

3 (-8) = -24:

40/15 + (-24)/15

40/15 - 24/15 = (40 - 24)/15:

(40 - 24)/15

A school dance committee has 14 volunteers. Each dance requires 3 volunteers at the door, 5 volunteers on the floor, and 6 float
siniylev [52]

There are 91 such ways in whih the volunteers can be assigned if two of them cannot be assigned from 14 volunteers.

Given that a school dance committee has 14 volunteers and each dance requires 3 volunteers at the door, 5 volunteers on the floor and 6 on floaters.

We are required to find the number of ways in which the volunteers can be assigned.

Combinations means finding the ways in which the things can be choosed to make a new thing or to do something else.

nC_{r}=n!/r!(n-r)!

Number of ways in which the volunteers can be assigned is equal to the following:

Since 2 have not been assigned so left over volunteers are 14-2=12 volunteers.

Number of ways =14C_{12}

=14!/12!(14-12)!

=14!/12!*2!

=14*13/2*1

=91 ways

Hence there are 91 such ways in whih the volunteers can be assigned if two of them cannot be assigned.
