Length = x
width = 2x
perimeter = 138in
in order to find perimeter you add length and width twice, so;
2(2x + x) = 138
2(3x) = 138
6x = 138
x = 23
since x = 23;
the length is 23in and the width is 46in
<h3>
Answer: 53,560 dollars</h3>
=======================================================
Explanation:
Having the salary increase by 3% means we can use the multiplier 1.03
Think of it like 100% + 3% = 1 + 0.03 = 1.03
The new salary is 52,000*1.03 = 53,560 dollars
----------------
The slightly longer way to do this is to first figure out how much 3% of 52,000 is
3% of 52,000 = 0.03*52,000 = 1560
Ricardo earns $1560 more dollars on top of the salary of $52,000
So overall his new salary is $1,560 + $52,000 = $53,560
----------------
Personally, I prefer the first method because it's quicker and it allows for multiple percentage increases to chain together. It also could be used to chain in percentage decreases as well.
For this case we have the following expression:
By definition, we have the expression undefined when the denominator is 0.
So:
Adding 5 to both sides of the equation:
Thus, the expression is undefined when
