Step-by-step explanation:
There is 6 sides on a rectangular prism
the top would be 6 x 4 = 24 and same for the bottom then I'll do the left amd right sides those are 20 and the front and back sides are 30 so I add all the sides so...
30 + 30 + 20 + 20 + 24 + 24 = 148
so 148 is our answer
Answer:
1. -3 on both side and m=4
2. +2 on both side and k=10
3. divide 3 on both side and n=6
x²/9 − (y + 1)²/81 = 1
-2y − 82 + 9x² = y²
9x² = y² + 2y + 82
9x² = y² + 2y + 1 + 81
9x² = (y + 1)² + 81
9x² − (y + 1)² = 81
