Answer:
four less than the quotient of a number cubed and seven, increased by three 
five times the difference of a number squared and six

nine more than the quotient of six and a number cubed, decreased by four

twice the difference of nine and a number squared

Step-by-step explanation:
Let n the number of interest we have this:
four less than the quotient of a number cubed and seven, increased by three 
five times the difference of a number squared and six

nine more than the quotient of six and a number cubed, decreased by four

twice the difference of nine and a number squared:

Assuming you mean sqrt(-144, we can use some properties of square roots to figure this out. sqrt(x*y) = sqrt(x) * sqrt(y)
We have sqrt(-1*144) = sqrt(-1) * sqrt(144). That would be i * 12, which is 12i.
y=-2.08
bring the 4.58 over to the other side of the equation and solve 2.5-4.58
According to the rules of math: multiplying comes before substraction(minus) so first multiply...
90×35×12455680= 39235392000
then minus 80 from the answer you got from multiplying.
39235392000-80= 39235391920
