Choose one of the figures above.
on a piece of graph paper sketch the figure from the top, front, and side views by shading in the appropriate number of boxes.
determine the number of faces in the figure. watch for “hidden faces.”
if the area of one of the faces is 4, what is the surface area for the figure?

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.
