Please answer fast, it's important... Q) find the volume of cube whose dimensions are (x+7y), (7x-y) and (xy-5).

Alona [7]

Answer:

$Volume = 7x^3y+48x^2y^2-7xy^3 -35x^2-240xy-35y^2$

Step-by-step explanation:

Given

Shape: Cube

Dimension: (x+7y), (7x-y) and (xy-5).

Required

Determine the volume

The volume is calculated by multiplying the dimensions:

$Volume = (x+7y) * (7x-y) * (xy-5)$

Evaluate the first 2 brackets

$Volume = [x(7x-y)+7y(7x-y)] * (xy-5)$

$Volume = [(7x^2-xy)+(49xy-7y^2)] * (xy-5)$

$Volume = [7x^2-xy+49xy-7y^2] * (xy-5)$

$Volume = [7x^2+48xy-7y^2] * (xy-5)$

Open brackets

$Volume = xy[7x^2+48xy-7y^2] -5[7x^2+48xy-7y^2]$

$Volume = 7x^3y+48x^2y^2-7xy^3 -35x^2-240xy-35y^2$

What is the value of f(1)? A. 0 B. 1 C. 2 D. 4

lara31 [8.8K]

Answer:

The value of f(1) is A. 0

Step-by-step explanation:

In this question, when they ask what is the value of f(1), they want you to tell them what is the "y" coordinate of the point with the "x" coordinate equal to 1. In our case, the point with the "x" coordinate equal to 1 has the "y" coordinate equal to 0. Therefore, the value of f(1) is A. 0
