A) List two examples of pairs of numbers that share a common factor.

B) List a variable pair with a common factor.
C) Why do u think ab+ac is called "simplified form"?

I don't really what they are asking me to do...
ummmm, anyone help me?

Math help needed here.

12 and 16 share 4

26 and 169 share 13

Well, I suppose part c answers part b ab and ac share factor a

I guess whoever wrote this considers ab + ac simpler than a(b+c)

Sure, I can help you understand and answer the questions.

A) To find two examples of pairs of numbers that share a common factor, you need to think of numbers that have a factor in common. A factor is a number that divides evenly into another number. For example, let's take the numbers 12 and 18. Both 12 and 18 can be divided evenly by the number 6, so they share a common factor of 6. Another example could be 8 and 16, which both have a common factor of 8.

B) To find a variable pair with a common factor, you can invent two variables and assign them values that have a common factor. For example, let's say you have the variables "x" and "y". You can assign values to them, such as x = 4 and y = 12. Here, both x and y share a common factor of 4.

C) The expression "ab+ac" is called simplified form because it represents the simplest possible way of expressing the common factor between the terms. In this case, both terms have the common factor of "a", so it can be factored out. When you factor out "a", the expression can be simplified to "a(b+c)". This simplification helps make the expression easier to work with, understand, and manipulate in mathematical calculations.
