6 = 2(x + 8) - 5x
6 = 2x + 16 - 5x
6 = 16 - 3x
3x = 16 - 6 = 10
x = 10/3
Volume of a cone = 1/3 r² π h
Volume of a cylinder = r² π h = 3 · V ( cone ) = 3 · 12 = 36 in³

Answer:
A 1
Step-by-step explanation:
The cube containing 125 = 5³ blocks will have a edge dimension of 5 blocks. The perimeter of one square face will be 4 times the edge dimension of the face, so will be 4×5 blocks = 20 blocks.
If 20 blocks = 20 units, then the edge of one block is 1 unit. Its volume is 1 unit³, or 1.
The appropriate choice is (A) 1 unit³ for the block volume.
Answer:
Step-by-step explanation:
Ok so 9x minus 11x you get -2x then the two y^2 cancel each other out to get -2x if the y^2 is separate from the x variable. However if its all one then it would be just 9 minus 11 to get -2 then putting the variable back on the end to get -2xy^2.
