Answer: ![=20,7872](https://tex.z-dn.net/?f=%3D20%2C7872)
Step-by-step explanation:
For this exercise it is important to remember the multiplication of signs. Notice that:
![(+)(+)=+\\\\(-)(-)=+\\\\(-)(+)=-\\\\(+)(-)=-](https://tex.z-dn.net/?f=%28%2B%29%28%2B%29%3D%2B%5C%5C%5C%5C%28-%29%28-%29%3D%2B%5C%5C%5C%5C%28-%29%28%2B%29%3D-%5C%5C%5C%5C%28%2B%29%28-%29%3D-)
In this case you have the following expression given in the exercise:
![(0,65-3,21)(-8,12)](https://tex.z-dn.net/?f=%280%2C65-3%2C21%29%28-8%2C12%29)
Then you can follow the steps shown below in order to solve it:
Step 1: You must solve the subtraction of the numbers 0,65 and 3,21. Then:
![=(-2,56)(-8,12)](https://tex.z-dn.net/?f=%3D%28-2%2C56%29%28-8%2C12%29)
Step 2: Now you must find the product of the decimal numbers above. In order to do that you must multiply the numbers.
(As you can notice, both are negative, therefore you know that the product will be positive).
Then, you get that the result is the following:
![=20,7872](https://tex.z-dn.net/?f=%3D20%2C7872)
A school custodian waxed a gymnasium floor that measured 20 feet by 20 feet. How many square feet did she have to wax?
If it's 20 feet * 20 feet = to
400 sq.ft
Hope this helps!
7,500 plus the commision is 525 now you add it to the 7,500 that will leave you with 8,025 now you subtract it from 185,000 so the answer will be 176,975
I'm glad if it helps :)
