1. You have a solid rectangular pyramid made of dough. Consider the cross sections that are formed when you

slice into the cube as described. Draw each slice and describe the resulting cross section (2 points each)

(a) A slice that cuts parallel to the base

(b) A slice that cuts perpendicular to the base through the vertex Triangle

(c) A slice that cuts perpendicular to the base but NOT through the vertex,

a) will show a cross section of either a SQUARE or RECTANGLE depending on if the pyramid is either a square or a rectangular pyramid

b) will show a cross section of a TRIANGLE,

c) will show a cross section of a TRAPEZOID

Step-by-step explanation:

(a) A slice that cuts parallel to the base will result into either a SQUARE or a RECTANGLE (depends on the length of the 4 sided base).

b) A slice that cuts perpendicular to the base through the vertex Triangle will result in a TRIANGLE.

(c) A slice that cuts perpendicular to the base but NOT through the vertex will result in a TRAPEZOIDAL SECTION.

d is correct

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
