Answer:
i’m pretty sure is A SAS
Step-by-step explanation:
The answer you are looking for is 3.5+3.5. This is because a doubles fact are any two of the same numbers that are added together.

In short, 4 and 6 are irrational. Everything else is rational.
============================================
Explanation:
A rational number is one in the form p/q where p,q are integers and q is nonzero. In the case of something like 3/5, we have p = 3 and q = 5.
Any terminating decimal can be converted to a rational number. Eg: 0.125 = 125/1000.
Any whole number is a rational number. Eg: 5 = 5/1.
Adding any two rational numbers leads to some other rational number.
Based on what is mentioned above so far, this means choices 1 through 3 are rational sums.
---------
Choice 4 is not rational because sqrt(2) is irrational. The rule is
irrational+rational = irrational
Choice 5 is a rational sum because sqrt(4) = 2 = 2/1
Choice 6 is irrational for similar reasons as choice 4. Here pi = 3.14... is irrational.
Step-by-step explanation:
Let’s set up a proportion.
6/20=x\100 (percent is always out of 100. set parts and wholes equal)
x=30
30 percent of the people are from out of state.
