I don’t understand this help me

Zarrin [17]

the property of a rectangle two opposite sides are the same. meaning the length that is X must have the same length on the other side right. Same thing as the side 2 4/5. so there are 2 of that same number. you're basically multiplying it by 2

expression

2x + 2(2 4/5) = P

if you don't understand that it's basically like this

x + x + 2 4/5 + 2 4/5 = P (it's the same as the above expression)

P = perimeter of rectangle

Outliers can be defined as numbers in a given data set that is varies from the other numbers in the data set.

We are given the data set :

11,12,19,20,20,20,21,21,22,22,25,27,30

There are outliers in this data set and they are:

Find the equation of a circle with a center at (7, 2) and a point on the circle at (-2, -5).

KatRina [158]

Answer:

(x-7)^2 + (y-2) ^2 = 130

Step-by-step explanation:

We need to find the length of the radius

the length of the radius is found by using the distance formula

r = sqrt( ( -2-7)^2+( -5 -2)^2)

sqrt( ( -9)^2+( -7)^2)

sqrt( 81+49)

sqrt(130)

The formula for a circle is

(x-h)^2 + (y-h) ^2 = r^2

where (h,k) is the center and r is the radius

(x-7)^2 + (y-2) ^2 = 130
