To begin with you multiply each term in the parentheses by each term in the second parentheses in the equation So then it would be

4x • 5x+4x • 2 + 4 • 5x+4 • 2

That then when you calculate it it would be

20x^2+8x+20x+8

Then you get the like terms.

20x^2+28x+8

Factor the polynomial completely

aliina [53]

We have $2x^2-8$ .

First let us factor the 2 to obtain,

$2(x^2-4)$

We can now see clearly that the expression inside the parentheses is a difference of two squares.

We now write the 4 as 2². So that we obtain the expression,

$2(x^2-2^2)$

Recall that

$a^2-b^2=(a+b)(a-b)$

Hence our expression becomes,

$2(x+2)(x-2)$

Therefore, when factored completely,

$2x^2-8=2(x+2)(x-2)$

A robot is expected to filter pollution out of at least 350 liters of air and water. It filters air at the rate of 50 liters per

s2008m [1.1K]

Answer:

$20W+50A\geq 350$

Step-by-step explanation:

we are given that A robot is expected to filter pollution out of at least 350 liters of air and water.

Also It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.

The inequality for number of minutes the robot should filter air (A) and water (W) to meet this expectations can be writte as follows:

$20W+50A\geq 350$

Hence the required inequality has been formulated.
