Peter makes two slices through a three-dimensional object. One plane is
parallel to the base; the cross-section is a square. The other plane is
perpendicular to the base; the cross-section is a rectangle. What three-
dimensional shape did Peter cut?

SPHERE

if you cut a sphere paralell to it's base, you get a circle

if you cut it perpendicular, you get  a circle

circle=circle so this works

CUBE

if you cut a cube paralell to it's base, you get a square

if you cut it perpendicular, you get  a square

square=square so this works

answer for #1 is c

answer for #2 is d

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
