The GCF is 5x
9x squared-15x squared = -6
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
The GCF is 15x.
If x>1 then the gcf is 15x. If x<1 then the gcf is 15.
-15x + 1
you just add 6x+9x to get 15x then minus 25 from 18 to get -7 thus the answer will be 15x-7
The GCF is x.
The GCF is 3x.
A decimal number
The GCF is 3.
The GCF is 1.
