Answer:
Step-by-step explanation:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
When you add the right side of the equation, you get 33.2, because they are the same problem but on side has brackets.
Hope this helps you.
A is the answere for your eqation to the problem
A formula<span> for the number of possible </span>combinations<span> of </span>r<span> objects from a </span>set<span> of </span>n<span> objects. For this, order is not important. We calculate it as follows:

I’m not exactly sure what the question is asking, but assuming that the equation is r=10b^2, then the answer would be r=40.
