Answer:

3 inches

Step-by-step explanation:

(2 + 2x)(3 + 2x) = 72

4x² + 4x + 6x + 6 - 72 = 0

4x² + 10x - 66 = 0

2x² + 5x - 33 = 0

Using quadratic formula:

x = (-5-17)/4, (-5+17)/4

x = 12/4 = 3

Which description does NOT guarantee that a trapezoid is isosceles?
babunello [35]

A trapezoid is isosceles if and only if

(1) The base angles are congruent

(2) The diagonals are congruent

(3) The opposite angles are supplementary

Answer:

Volume of rectangular prism = 10/9 inch³

Step-by-step explanation:

Given:

Size of each cube = 1/3 inch

Find:

Volume of rectangular prism

Length of rectangular prism = 2/3 inch

Width of rectangular prism = 3 x [1/3]

Width of rectangular prism = 3/3

Width of rectangular prism = 1 inch

Height of rectangular prism = 5 x [1/3]

Height of rectangular prism = 5/3 inch

Volume of rectangular prism = Length x Width X Height

Volume of rectangular prism = [2/3] x [1] x [5/3]

Volume of rectangular prism = 10/9 inch³
