Answer:

-282x

Step-by-step explanation:

<em>firstly, you have to know these:</em>

<em>=> y + x + x = 2x + y</em>

<em>=> y + x + x = 2x + y=> 3x - x +y -4y = 2x -3y</em>

<em>=> y + x + x = 2x + y=> 3x - x +y -4y = 2x -3y=> 2(10x -5x +2y) = 2(5x+2y) = 10x +4y</em>

<em>Simplify: −6(14x -23x + 56x)</em>

<em>-</em><em>6</em><em>(</em><em>70x</em><em> </em><em>-</em><em>23x</em><em>)</em>

<em>-6.47x</em>

<em>-</em><em>282x</em>

Hope this helps ^-^

What is the value of x (distance from the edge of the screen to the end of the wall) if the area of the screen is 40 m^2?
erica [24]

The value of x that is the length from the edge of the screen to the end of the wall is equal 3. This is derived from an equation which serves as a function of the Area. See the solution below.

<h3>

What is the calculation for the solution above?
</h3>

Recall that the area of the entire wall is 40m².

(10-2x) (16- 2x) = 40

Expanding the brackets, we have

160-20x-32x + 4x² = 40
4x² - 52x + 120 = 0
x² - 13x +30 = 0

Using the quadratic equation

x = (-b±√b²-4ac)/2a

Where a = 1
b  = 13
c = 30

x = (13 ± 7)/2

Thus x = 10; or x = 3.

x cannot be the answer because it invalidates 16-x<0;

Hence, the correct answer is x = 3
