Fill in the bubble next to all the doubles facts you could use to find the sum of 3+2? 2+2 5+5 3+3 1+1

Step-by-step explanation:

The given sum is

which is equal to 5.

So, the doubles facts that can help to solve the given sum must be also equal to 5, let's see

As you can observe, neither of them can be used to solve the given sum, because they are different thatn 5.

Therefore, none of the above is the answer here.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
