Step-by-step explanation:
Tell me if you need an explanation
We can rewrite this by subtracting the right side to get
... 3^(-x) -x^3 -x = 0
A graphing calculator shows this to have a solution near x=0.5.
_____
There are no algebraic means for solving such a combination of exponential and polynomial functions.
Answer: 5
Step-by-step explanation:


5
4.
4x - 36 = 2*(x+7) => 4x - 36 = 2x + 14 => 4x - 2x = 50 => x = 25 => DG = 4*25 - 36 = 64.
