Drag the tiles to the correct boxes to complete the pairs. Match each cross section with its perimeter.
a cross section parallel to the base of a
right rectangular prism that is 10 inches
long, 3 inches wide, and 14 inches high
a cross section perpendicular to the
base of a cube with 12-inch edges
a cross section perpendicular to the
base and passing through the
diagonals of the base and opposite
face of a right rectangular prism that is
inches long, 12 inches wide, and 4
inches high and measures 13 inches
along the diagonal of the base
a cross section parallel to the base of a
cube whose edges are 16 inches each

11) obtuse

13)right

15) acute

use a calculator or a graph

x=-2

step-by-step explanation:

i began by flipping the problem to give me x= on the left (keeps it clearer for me).   so my problem simply became 10x-3=4x-6.  

1)   subtract 4x from the right side, which equals 0.   you do the same to the left of the equal as the right; therefore, subtract 4x from 10x, leaving 6x on the left.

              10x-3=4x-6   :   4x-4x on the right leaves only the -6        

2)             6x-3= 0-6 :    

                6x+3=   -6

3) divide

we are given scale of 2 units.

on graph paper the space is 2.5 cm.

length of glass = 8 units.

8 units = 2 units +2 units +2 units +2 units.

each 2 unit is = 2.5cm.

therefore,

8 units = 2 units +2 units +2 units +2 units = 2.5+2.5+2.5+2.5= 10cm.
