Answer:
18 should be added
Step-by-step explanation:
So we have one 10 and one 11 in this data set, and we need to figure out which number we need to add to get a mean of 13
let's make this unknown number x
to find the mean, we add up all the values of the numbers on the data set, and divide it by how many numbers we have.
we have 3 numbers, and our numbers are 10, 11, and x. When we add 10, 11, and x together, and then divide by 3, the value is 13
as an equation we will have:
(10+11+x)/3=13
combining like terms in the numerator, it will be:
(21+x)/3=13
We need to solve this equation, and the denominator of 3 just makes harder to do that.
Clear the fraction by multiplying both sides by 3
21+x=39
subtract 21 from both sides
x=18
so that means that 18 should be added to the data set to get a mean of 13.
Hope this helps!

A rectangle has area x3 + 3x2 - 18x in.2 and width x + 6 in. What is the length in inches?
Answers
Answer:
HOPE THIS HELPS
Step-by-step explanation:
The area = length * Width.
We know the width = X+6 inches and Area = x^3+3x^2–18x.
This problem can be solved just by dividing the area by width and we get a quotient as X^2–3x.
So the length is x^2–3x inches.
The length of the rectangle is [tex]\rm x(x-3)[/tex].
Given
The area of the rectangle = [tex]\rm x^3+3x^2-18x[/tex] square inches
The width of the rectangle = x + 6 inches
Area of the rectangleThe area of the rectangle is equal to the product of length and width of the rectangle.
Let the length of the rectangle be L.
The area of the rectangle is given by;
[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\\rm x^3+3x^2-18x= L \times (x+6)\\\\L=\dfrac{ x^3+3x^2-18x}{x+6}\\\\L = \dfrac{ x(x+6)(x-3)}{x+6}\\\\ L = x (x-3)[/tex]
Hence, the length of the rectangle is [tex]\rm x(x-3)[/tex].
