To Find : . how many cubic feet would a billion dollars occupy?

Solution :

Length =6.14 inches

Width =2.61 inches

Height = 0.0043 inch

Since dollar bill is in cuboid shape .

Volume of 1- dollar bill = length*width*height

                                      = 6.14*2.61*0.0043

                                      = 0.06890922 cubic inches.

no, because the sides are not congruent

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
