Dana earns $765 a week.
4 days * 15 * 12.75= $765
Monique earns $637.50 a week.
5 days * 10 * 12.75= $637.50
The difference is $127.50 a week.
To solve this, we have to complete the square of
To do this with halve the and get rid of the x, then get rid of the power on , and then put them all in brackets, and the square the bracket, like so:
becomes
However does not equal
If we expand we get instead.
So to make it equal, all we do is subtract 1.
So when we complete the square of , we get
---------------------------------------------------------
So becomes:
x + 1 = ±√6
x = -1 ± √6
______________________________
Answer:
x = -1 ± √6
Answer:
Both versions of the expression equal the exact same amount;one is just much shorter.Simplifying algebraic expressions is the same idea,except you have variables in your expression.So,Basically you're turning a long expression into something you can easily make sense of
