The GCF stands for greatest common factor. To represent a sum by its GCF we need to use the distributive property and we need to first find the GCF of the numbers. Let's break each number by its factors:

We now multiply the numbers that appear on both.

We now apply the distributive property:
(x-5) = 0 or (x+2)=0
so x could be 5 or -2
i guess, u can check it with calculator
6 people go in each car because since there is only six seats 6x1 equal 6 and there i no remainder
The answer would be B) -5, 3. The roots can be found where the graph crosses the x-axis, which on this graph is -5 and 3.
