Step-by-step explanation:
If one marker is 6/20. (0.3) So, 6/20*111= 333/10. That's $33.30.
-x⁴+ 6x³- 7x²- 4x - 4
Order from least to greatest exponent (the variable, which is x in this case, is always first by the way in terms of order, then integers). This point of this problem is essentially to just rearrange the original equation.
Simplify by combining the real and imaginary parts of each expression
