x²y²-4x³+12y

4-x²

<h3>Which algebraic expressions are polynomials?</h3>

A polynomial is an expression of the form:

p(x) = aₙ*xⁿ + ...+ a₂*x² + a₁*x  + a₀

Where all the exponents of the variable are whole numbers, and in this case we have only one variable x, but we could have any number of variables.

With that in mind, the options that are polynomials are:

3.9x³-4.1x² + 7.3

x²y²-4x³+12y

4-x²

These 3 expressions are polynomials.

Create an equivalent expression:<br><br> 2(3x -1) - 3x +4<br><br> Show all steps please! In detail!
Vsevolod [243]

Answer:

The answer is 3x+2

Step-by-step explanation:

2(3x-1)-3x+4

I did distributive property on 2(3x-1) how I did that was I multiplied 2 times 3x which is 6x (2 times 3x=6x). Then I multiplied 2 times -1 which equals -2          (2 times -1=-2).

new expression:

6x-2-3x+4

I combined all the numbers with the variables (6x and -3x) and by subtracting both of them you get 3x (6x-3x=3x). After that you combine -2 and 4 which equals 2 (-2+4=2).

This is now the final expression (your answer):

3x+2

evablogger [386]

Answer:

15 = 9 + 5j

When you want to make words become an equation, the word <em>is</em><em> </em>usually means <em>= </em>and <em>more</em><em> </em>usually means <em>+</em>.

In this case, we have 15 is 9 more than 5j.

We can rewrite this as 15 = 9 + 5j.
