Is 3x+1+2x-7=x+22 is a distributive property?

No

Step-by-step explanation:

The associative property states that you can re-group numbers and you will get the same answer and the commutative property states that you can move numbers around and still arrive at the same answer.

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products. [The distributive property tells us how to solve expressions in the form of a(b + c).]

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
