Answer:

n = 60°

Step-by-step explanation:

60° + n + 60° = 180° ( straight line angles)

-> n + 120° = 180°

-> n = 180° - 120°

-> n = 60°

The volume of a rectangular box is 2x(2x + 5)(2x – 3). (Drawing is not to scale.)
Anarel [89]

Answer:

Option B. The volume is the product of the area of the base, 2x(2x + 5), and the height, 2x – 3

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The volume of a rectangular prism is equal to

V=BH

where

B is the area of the base of the prism

H is the height of the prism

In this problem we have

The area of the base B is equal to

B=2x(2x+5)\ units^2

The height H is equal to

H=2x-3\ units

therefore

The volume is equal to

V=2x(2x+5)(3x-3)\ units^3

The volume is the product of the area of the base, 2x(2x + 5), and the height, 2x – 3

A Trapezoid has an area of 150 square feet. the Bases are 14 feet and 16 feet. write an equation to determine the height of the
JulsSmile [24]
Given:
Area = 150 square feet
Bases = 14 feet and 16 feet

Find the height of the trapezoid.

Let us use the formula of finding the Area of a trapezoid to get the value of its height.

A = (a+b)/2 * h
150 ft² = (14ft + 16ft)/2 * h
150 ft² = 15ft * h
150 ft² / 15 ft = h
10 ft = h

The height of the trapezoid is 10 feet.
