Explain why all integers are rational numbers, but not all rational numbers are integers

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.

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?
