What is the equation equivalent to?

To turn  into an absolute value inequality we do the following:
First get the average between 1.3 and 2.1. To do this we add 1.3 to 2.1 and then divide by two.

Now that we have the average we can start to create the absolute inequality 

Insert our average in the middle

Subtract subtract 1.3 from 1.4  and 1.4 from 2.1 which both will  = 0.4. Now setup your absolute value.
 

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.
