A) 8
B) 10
C) 12
D) none of the above

A) 8

Step-by-step explanation:

The average of two numbers is 7.

6 and x have an average of 7.

sum of terms / number of terms = average

(6 + x)/2 = 7

6+x = 14

x = 8

The number is 8.

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

the answer is 13

5*5=25

12*12=144
