Answer:

x is equal to 3/2

Step-by-step explanation:

Let's solve it!

5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)

expand:

20x - 50 + 10x = 8x - 12 + 2x - 8

group like terms:

30x - 50 = 10x - 20

factor out common multiples:

3x - 5 = x - 2

group terms again:

3x - x = -2 + 5

2x = 3

and divide both sides by two:

x = 3/2

A rectangle has a length of x inches and a width 2 inches less than the length.If the dimensions were doubled, what would be the

zheka24 [161]

If the dimensions of the rectangle were doubled, the area in square inches is: $Area = 4x^2 - 8x$

Let the length of the rectangle be L.

Let the width of the rectangle be W.

<u>Given the following data:</u>

Length = x inches

Width = x - 2 inches

If the dimensions of the rectangle were doubled, the value of L and W becomes;

$L = 2x$

$W = 2(x - 2)$

Mathematically, the area of a rectangle is given by the formula;

$Area = Length$ × $Width$

$Area = 2x$ × $2(x-2)$

$Area = 2x$ × $2x - 4$

$Area = 4x^2 - 8x$ square inches.

V= x*(10-2x)(8-2x)

for greatest volume, differentiate v w.r.t x and equate to 0,

dv/dx= (10-2x)(8-2x) + x(-2)(8-2x)+ x(10-2x)(-2)=0

you get x from solving the quadratic equation. volume will be max at that x
