7. 72 is 49

1225 = 52*72
It is 72.It is 72.It is 72.It is 72.It is 72.It is 72.
9*8=72
72 divided by 1 = 72 72 multiplied by 1 = 72
I do not believe this is possible. Here's why. The factors of 72 are 36*2 18*4 12*6 9*8 Now to get a positive 72 both the factors must be negative so let's just add all the possible factors and see if we can come up with -19 -36 + (-2) = -38 -18 + (-4) = -22 -12 + (-6) = -18 -9 + (-8) = -17 So there you have it... no -19. I hope this is right!
