=x^4−2x^3−20x^2+46x−21
if you can give me brainliest that would be great :)
For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: total cost
We write the algebraic expression that models the problem.
We have then:

Simplifying we have:

Then, by the time the cost is equal to $ 300 we have:

From here, we clear the value of x.
Answer:
an algebraic expression for the problem is:

Answer:
no
Step-by-step explanation:
8a+8b are not equivalent 6a+5b
L(which is length) is equal to 42 divided by width which is 6. so the equation is L=42/6
