-4x -4x
-1x=-4
x=4
Answer:
Volume: 112 m³.
Surface area: 172 m².
Step-by-step explanation:
The volume is the base times height times length. So, the volume will be 2 * 8 * 7 = 16 * 7 = 112 m³.
The surface area is 2lw + 2lh + 2wh. l = 8; w = 7; h = 2.
2(8)(7) + 2(8)(2) + 2(7)(2) = 2 * 56 + 2 * 16 + 2 * 14 = 112 + 32 + 28 = 112 + 60 = 172 m².
Hope this helps!
Answer:
-1
Step-by-step explanation:
You can write it as...
Carry the 4x
Then use the quadratic formula to solve, since you want to find the negative solution, you don't need to find the positive solution, so we will have
Therefore our answer is -1
