The top and bottom of a right rectangular prism are 4 inches long and 4 inches wide. What is true about the other faces (front,
back, left, and right)? All four of the remaining faces will have a height of 4 inches.
There is not enough information to tell what the other faces will look like.
Two of the remaining faces will be 4 inches wide.
All four of the remaining faces will be 4 inches wide.
1) factor the denominators: 2b/(b-1)2 - 2/ (b-1)2 2) MAKE SURE YOU HAVE A COMMON DENOMINATOR 3) combine the numerators: 2b-2/(b-1)2 4) distribute 2 from numerator: 2(b-1)/(b-1)2 5) simplify; answer is 2/(b-1)
