Answer:
==========================================================
Explanation:
The endpoints of this compound inequality are 1.2 and 2.2
Add up the endpoints to get 1.2+2.2 = 3.4
Divide that result in half getting 3.4/2 = 1.7
The midpoint between 1.2 and 2.2 is 1.7
The distance from 1.7 to 1.2 is 0.5 units after we subtract the values (1.7-1.2 = 0.5). Also, from 1.7 to 2.2 is 0.5 units as well (2.2 - 1.7 = 0.5)
The compound inequality converts to the absolute value inequality
The portion h-1.7 represents the distance h is from 1.7; we want this distance to be 0.5 or smaller. The use of absolute value is to ensure the result h-1.7 is never negative.

Calculate the product.
Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:
Now multiply the terms with the same base by adding their exponents.
Finally,, add the numbers together to get your final answer.
