Which of the following demonstrates the commutative property of multiplication?
5(2a − 3) = 10a − 15

10a − 15 = (2a − 3) ⋅ 5

5(2a − 3) = (2a − 3) ⋅ 5

(5 ⋅ 2a) − 3 = 5(2a − 3)

Which expression is not a polynomial?

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer
