Answer:
if the net where to be folded into a cube number 6 will be opposite number 1.
Step-by-step explanation:
If the net where folded into a cube the number that will be opposite to number 1 will be 6 . The best way to know this is by simply cutting a paper similar to the shape of the net above and numbering them as required . Folding the paper to form a cube, you will discover that the number 6 is opposite the number 1 value.
Or from the picture you will notice when you close the number 5, the number 4 will be on top of number 1 and the 6 can then be bend down which makes it opposite the number 1.
For 5a+5b+5c=-20
A= -4 - b - c
B= -4 - a - c
C= -4 - a - b
———————————
4a+3b+3c=-6
A= -3/2 - 3b/4 - 3c/4
B= -2 - 4a/3 - c
C= -2 - 4a/3 - b
———————————
-4a+3b+3c=9
A= -9/4 + 3b/4 + 3c/4
B= 3 + 4a/3 - c
C= 3 + 4a/3 - b
