Answer:

15^4+2^3−8^2−22−15

Step-by-step explanation:

(3^2−2−3)(5^2+4+5)

Distribute:

<u>3(5^2+4+5)</u> ⋅ ^2−2(5^2+4+5) − 3(5^2+4+5)

15^4+12^3+15^2 <u>− 2(52+4+5)</u> − 3(52+4+5)

15^4+12^3+15^2 − 10^3−8^2−10 <u>− 3(52+4+5</u>)

15^4+12^3+15^2 − 10^3−8^2−10 − 15^2−12−15

Combine like terms:

15^4<u>+12^3−10^3</u>+15^2−8^2−15^2−10−12−15

15^4+2^3<u>+15^2−8^2−15^2</u>−10−12−15

15^4+2^3−8^2<u>−10−12</u>−15

15^4+2^3−8^2−22−15

15^4+2^3−8^2−22−15

hope it helps :)

Aaron bought a set of plastic ice cubes with a mixture of water and air inside.
LekaFEV [45]

Answer:

Volume of water and air is 3,000 mm³

Step-by-step explanation:

Given:

Length of base = 15 mm

Width of base = 20 mm

Height of figure = 30 mm

Find:

Volume of water and air is inside each of the plastic ice cubes.

Computation:

Height of each rectangular pyramid = Height of figure / 2

Height of each rectangular pyramid = 30 / 2

Height of each rectangular pyramid = 15 mm

Volume of each rectangular pyramid = lbh / 3

Volume of each rectangular pyramid = [15 × 20 × 15] / 3

Volume of each rectangular pyramid = [4,500] / 3

Volume of each rectangular pyramid = 1,500 mm³

Volume of water and air is inside each of the plastic ice cubes = 2 × Volume of each rectangular pyramid

Volume of water and air is inside each of the plastic ice cubes = 2 × 1,500

Volume of water and air is inside each of the plastic ice cubes = 3,000 mm³
