Question

Is 8 a factor of 63q + 15

Answer

No

  • Q: What is the expression we need to work with? A: 63q + 15.
  • Q: What is the definition of a number being a factor of an expression? A: A number is a factor of an expression if it divides the expression without leaving any remainder.
  • Q: Can 8 divide 63q + 15 without leaving any remainder? A: Let's simplify the expression by factoring 8 from it. 63q + 15 = 8(7q + 1) + 7. Since 8 does not divide 7, there is a remainder of 7. Therefore, 8 is not a factor of 63q + 15.
