Answer:
423
Step-by-step explanation:
Answer:
I'm not sure what 15y3 is, but I'll take a guess.
If the only numbers are 15, 3, and -40, then the greatest common factor is 1.
If the only numbers are 15 and 3, then it's three.
If the only numbers are 15 and -40, it would be 5.
First plug in the numbers 5 x 8 = 40
40-4y+6x8=48
40-4y+48
35+35+35+35+35+35+35+35+35+35+35+35
Or
35×12
=420
