Write an equation to find the missing side lenght. use ? for the number you do not know

Whitepunk [10]

There isn't enough information; however, let's say you were to find the missing side length of a rectangle. The perimeter is 52 and the two given side lengths are both 16. You would set up an equation to find the missing side lengths:
52 = 16 + 16 + ? + ?
52 = 32 + ? + ?
20 = ? + ?
Since this is a rectangle, the two other sides have to be equal. Therefore, you would divide the number by 2.
10 = ?

What is the slope of the line?

Katyanochek1 [597]

Answer:

1

Step-by-step explanation:

slope (k) is the rise over run of the line

a way of finding the slope if you have two dots of the line is:

$k \: = \frac{y2 - y2}{x2 - x2}$

here the dots that belong to the line that you can most easily see are:

A(-6,0)

B(0,6)

by inserting the values into the euquation you get:

$\frac{6 - 0}{0 - ( - 6)} = \frac{6}{6} = 1$

good luck with your maths solving
