Answer:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
Step-by-step explanation:
Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.
Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.
All they give us is that Elena has less than $20 in her bank account.
So your answer may look like this:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.

Given data:
The first given length is AC=53.
The second given length is AB= 45.
The expression for the Pythagoras theorem is,

Here, consider only positive sign of BC length as side cannot negative.
Thus, the BC length is 28.
