A pyramid and a cube monument are being created for a display. Their volumes are supposed to be the same. The volume of a pyramid is ⅓ times the height times the base area (V=13hb). The pyramids height (h) and base area (b) are given: h=(3x+6) and b=x2+2x+1. The volume of the cube is V=x3+4x2+27. What value of x would make the volumes the same? What is the volume of the cube? SHOW WORK PLEASE!

What are the coordinates of the midpoint of ab? ,1/2) /2,-1) ,-3/2) /2,-2)

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Select the correct answer from each drop-down menu. a system of equations and its solution are given below. system a complete the sentences to explain what steps were followed to obtain the system of equations below. system b to get system b, the equation in system a was replaced by the sum of that equation and times the equation. the solution to system b the same as the solution to system a.]
