Both of the correct answers equal 2,400 points. Why do they have the same value?

because 200 + 200 12 times is equal to 200 x 12

Sample Multiplication is a short way to write repeated addition. So 200 •12 means the same as 200 + 200 + . . . + 200.

Step-by-step explanation:

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 .
