By definition, the standard form of a polynomial is given by:

ax ^ n + ... + bx ^ 3 + cx ^ 2 + dx + e

We then have the following polynomial:

2x ^ 2-4x ^ 3 + \frac{6}{3}

Rewriting in its standard form we have:

-4x ^ 3 + 2x ^ 2 + 2

We realize that the polynomial has three terms, therefore, it is a trinomial.

The largest exponent of the polynomial is three and therefore we have a trinomial of degree three.

Answer:

-4x ^ 3 + 2x ^ 2 + 2

Three degree trinomial.

Mika used these steps to solve the equation 5x−12=−2+5(x−2)
e-lub [12.9K]
5x−12=−2+5(x−2)
multiply 5 by all in parentheses first
5x - 12= -2 + (5*x) + (5*-2)
5x - 12= -2 + 5x - 10
5x - 12= 5x - 12
if you subtract 5x from one side and add 12 to the other the solution is:
0= 0

This equation is one that is always true. No matter what number you put in for x, it will always be true.

Example:
5x - 12= 5x - 12
5(4) - 12= 5(4) - 12
20 - 12= 20 - 12
8= 8

Example:
5(-100) - 12= 5(-100) - 12
-500 - 12= -500 - 12
-512= -512

This will happen no matter what number x is.

ANSWER: D) All values of x make the equation true.

Hope this helps! :)

A students cost for last semester at her community college was $2500. She spent $475 of that on books.what percent of last semes
max2010maxim [7]
It is 19%!! :) an explanation is:
We assume, that the number 2500 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 2500, so we can write it down as 100%=2500.
4. We know, that x% equals 475 of the output value, so we can write it down as x%=475.
5. Now we have two simple equations:
1) 100%=2500
2) x%=475
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=2500/475
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 475 is what percent of 2500

100%/x%=2500/475
(100/x)*x=(2500/475)*x - we multiply both sides of the equation by x
100=5.2631578947368*x - we divide both sides of the equation by (5.2631578947368) to get x
100/5.2631578947368=x
19=x
x=19

now we have:
475 is 19% of 2500

Answer:

x²

Step-by-step explanation:

Let "d" represent the divisor (what goes in the blank). Then you have ...

... (x²y)/d = y

Multiplying by d gives ...

... x²y = yd

And dividing by y gives the desired value:

... x² = d

The divisor is x².
