Answer:

the answer to the question is 8x⁴- 5x²y² - 6y⁴

Step-by-step explanation:

the normal way of using BODMAS is apply to all polynomial equations.

subtracting -6x⁴- 3x²y² + 5y⁴ from 2x⁴ - 8x²y² - y⁴.

polynomial of the same degree is very easy to calculate. this equation is having the same degree of polynomial all through, therefore:

Applying Bracket to the equation

2x⁴ - 8x²y² - y⁴- ( -6x⁴- 3x²y² + 5y⁴)

Open the bracket

2x⁴ - 8x²y² - y⁴ +6x⁴+3x²y² - 5y⁴

collects the likes terms

2x⁴ +6x⁴- 8x²y² +3x²y² - 5y⁴ - y⁴

The final answer is =

8x⁴- 5x²y² - 6y⁴

An atrium is being designed to house an exhibit of tropical birds. The atrium must enclose 250,000 cubic feet of space, and the

9966 [12]

The proposed design of the atrium (V < V') is possible since its volume is less than the maximum possible atrium.

<h3>Can this atrium be built in the rectangular plot of land?</h3>

The atrium with the maximum allowable radius (R), in feet, is represented in the image attached. The real atrium is possible if and only if the real radius (r) is less than the maximum allowable radius and therefore, the real volume (V), in cubic feet, must be less than than maximum possible volume (V'), in cubic feet.

First, we calculate the volume occupied by the maximum allowable radius:

V' = (8 · π / 3) · (45 ft)³

V' ≈ 763407.015 ft³

The proposed design of the atrium (V < V') is possible since its volume is less than the maximum possible atrium. $\blacksquare$
