Answer:

Step-by-step explanation:
I am assuming this problem reads 
- So let's start on the outside and work our way towards the middle
- Starting with the
, this can be simplified to
Now we have 
- Now simplifying what is inside the parenthesis we get
- Combining what we have the simplified for of the problem becomes:

Rational numbers are numbers which can be written as a fraction (the formula is p/q). They don't include roots we can't solve in order to get a whole number and pi.
A. 776, pi, 25.209, √9 ---> NO (because of pi)
B. 726, 7/34, 20.209, √9 ---> YES
C. √3, 7/39, 20.3, √9 ---> NO (because of √3)
D. 726, 7/34, 20.209, √5 ---> NO (because of √5
Note that √9 = 3, so it IS a rational number.
2x^2 + 2y^2 + 2xy I think
Answer:
5/10 or 1/2
Step-by-step explanation:
Beth ate 2/10 so 2/10+3/10+2/10=5/10=1/2
Answer:
1/2
Step-by-step explanation:
Slope is rise over run. Starting from (0, 2), go up and move right until you reach another point. So you go up 1 unit and move right 2 units.
