Step-by-step explanation:

3(4 *to the power of 2* - 3*to the power of 2*)

3(4²-3²)
3(16-9)
3(7)
21

24-23 x 3

24-23×3
24-69
-45

3*to the power of 3* - 3*to the power of 2

3³-3²
9-6
3

(6*to the power of 2* - 3) (9*to the power of 2* - 70)

(6²-3)(9²-70)
(36-3)(81-70)
(33)(11)
363

Hence, Option d. is the correct answer because it gives answer 3 when it is solved.

A bathtub is the shape of a rectangular prism. The dimensions are 5 1/2 ft times 2 1/2 ft times 2 3/4 ft. What is the volume of

Sav [38]

Answer:

$37 \frac{13}{16} ft^3$

Step-by-step explanation:

A rectangular prism is also know as a cuboid.

The dimensions of the rectangular prism shaped bath tub are 5½ ft * 2½ ft * 2¾ ft.

The volume of a cuboid (rectangular prism) is given as:

V = L * B * H

Hence, the volume of the bath tub is:

V = 5½ * 2½ * 2¾

V = 11/2 * 5/2 * 11/4

V = 605 / 16 = $37 \frac{13}{16} ft^3$

The volume of the bath tub is $37 \frac{13}{16} ft^3$
