Answer:3/2
how i did this
Add 11 to both sides.
4x=5+1
Simplify 5+15+1 to 66.
4x=6
Divide both sides by 4
x= 6/4
Simplify 6/4 to 3/2
Awnser
x=3/2
Sorry if not helpful just trying my best :)

EXPLANATION
The given polynomial is

where a=1,b=k, c=30
Let the zeroes of this polynomial be m and n.
Then the sum of roots is

and the product of roots is

The square difference of the zeroes is given by the expression.

From the question, this difference is 169.
This implies that:





We substitute the values of k into the equation and solve for x.


The zeroes are given by;

Answer:
the number of cookies ordered
Step-by-step explanation:
When an equation is written in the form ...
(left variable) = (some expression involving one or more right variables)
we usually describe the "left variable" as the "dependent variable" and the "one or more right variables" as the "independent variable(s)".
Here, the equation is given as ...
C = 3s + 30
__
This tells you C is the dependent variable, and s is the independent variable. The description also says "C is the number of cookies." Since you know that the dependent variable is the number of cookies, you can answer the question ...
the dependent quantity is the number of cookies ordered. (matches the first choice)
