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:

The picture of the question in the attached figure

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

Solve: 16x2 − 80 = 0 Round the answer to the nearest hundredth.

Leto [7]

Answer:

x = ±2.24

Step-by-step explanation:

16x² - 80 = 0

16x² = 80 (Add 80)

x² = 5 (Divide by 16)

x = ±√5 (Square root both sides)

≈ 2.24, -2.24
