Look at the pair of equivalent expressions. 36 + 8 = ? (9 + 2) what number is missing from the expression?

? = 4

4 is the number missing on the right.

Step-by-step explanation:

Check out the 8 on left. It has become a 2 on the right. How did that happen?

What do you have to multiply the 2 by to get 8?

Before I answer, check out the 9 on the right. What did you have to multiply it by to get 36? The answer to that is 4 isn't it?

What about the 2. Don't you have to multiply it by 4 to get 8?

36 + 8 = 4(9 + 2) The distributive property on the right will produce the numbers on the left.

So ? = 4

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 .
