All of my friends are disagreeing be the tie breaker and explain

1. what expression would be the same as 6x+x+0 2. find the prime factorization of 60 3. write the expression for 6 + x in words.

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?

Solve the equation: x - 9 = -6 + 5 a. 21 b. 7 c. 14 d. 2
