**Answer:**

x=4 x=-2

**Step-by-step explanation:**

x+4 x

----------- = ------------

4 x-2

Using cross products

(x+4)(x-2) = 4x

FOIL

x^2 -2x +4x -8 = 4x

Combine like terms

x^2 +2x -8 = 4x

Subtract 4x from each side

x^2 +2x-4x -8 = 4x-4x

x^2 -2x-8 =0

Factor

What 2 numbers multiply to -8 and add to -2

-4*2 =-8

-4+2 = -2

(x-4) (x+2) =0

Using the zero product property

x-4+4 =0+4 x+2-2=0-2

x=4 x=-2

Y=16/13x-7/13

**Step-by-step explanation:**

Answer:

The percentage change in volume between cylinder A and cylinder B is 50%

Step-by-step explanation:

The volume of a cylinder is given by the formula

V= πr^2h

For cylinder A, where r=7 and h= 5, π=22/7

V= π * 7^2 * 5

V= π * 49 * 5

V= 769.69 cubic inch

For cylinder B

V= 490π

V= 1539.3804 cubic inch

The percentage change in volume between cylinder A and cylinder B

=[ (VA- VB)/VB] *100

=( 1539.3804 - 769.69) / 1539.3804

= 0.5000 * 100

= 50%
