5x - 4 = 16
Add four to both sides
5x = 20
Divide both sides by 5
x = 4

Answer:
21 sq unit :3
Step-by-step explanation:
(this is what I got)
The expression (2x+2)*(x^2+3x-2) is the same as 2x*(x^2+3x-2)+2*(x^2+3x-2)
Basically we are going to have 2x times all of (x^2+3x-2)
And then we add on 2 times all of (x^2+3x-2)
Let's distribute through each piece
For the first part...
2x*(x^2+3x-2) = 2x*(x^2)+2x*(3x)+2x*(-2)
2x*(x^2+3x-2) = 2x^3+6x^2-4x
And then the second part..
2*(x^2+3x-2) = 2*(x^2)+2*(3x)+2*(-2)
2*(x^2+3x-2) = 2x^2+6x-4
-----------------------------------------
Putting this all together, we can say
(2x+2)*(x^2+3x-2) = 2x*(x^2+3x-2)+2*(x^2+3x-2)
(2x+2)*(x^2+3x-2) = 2x^3+6x^2-4x+2x^2+6x-4
(2x+2)*(x^2+3x-2) = 2x^3+8x^2+2x-4
-----------------------------------------
The final answer is 2x^3+8x^2+2x-4
