The first thing you need to know is f is the greatest common factor
here they are asking you for 3x meaning you power ( ^) can't go greater than 3
here are two forms
5x^2+8x^3+1
another one
2z^3-y^2+6
hope this helps
Kayla is correct because if she has 1,000 and Mack has 999, then that means he needs only one more Apple to be equal with Kaylas amount of apples . 999+ 1 = 1,000
try using the app Photomath for numbers 1-3!
Y=35
Z=112
Hope this helps you and you have a good day and yes I did calculate this
