Are 12x^2y^3z and -45zy^3x2 like terms? explain why or why not.
Alex787 [66]

Here in the second term I am considering 2 as power of x .

So rewriting both the terms here:

First term: 12x²y³z

Second term: -45zy³x²

Let us now find out whether they are like terms or not.

"Like terms" are terms whose variables (and their exponents such as the 2 in x²) are the same.

In the given two terms let us find exponents of each variable and compare them for both terms.

z : first and second term both have exponent 1

x: first and second term both have exponent 2

y: first and second term both have exponent 3

Since we have all the exponents equal for both first and second terms variables, so we can say that the two terms are like terms.

(6x3 + 3x² + 3) + (2x - 5x + 1)<br> the sum is?
laiz [17]
<h2>Answer:</h2><h2><em><u>8x^3 + 3x^2 - 5x + 4 is the answer.</u></em></h2>

Step-by-step explanation:

(6x^3 + 3x² + 3) + (2x^3 - 5x + 1)

6x^3 + 2x^3 = 8x^3

3x^2 + 0 = 3x^2

-5x + 0 = -5x

3 + 1 = 4

8x^3 + 3x^2 - 5x + 4 is the answer because you have to put all the terms that were solved together. This will lead to 8x^3 + 3x^2 - 5x + 4. And, standard form is ax^2 + bx + c. So, 8x^3 + 3x^2 - 5x + 4 is the answer.

<em><u>8x^3 + 3x^2 - 5x + 4</u></em>

<em><u></u></em>

Hope this helped,

I am Lyosha [343]
Part A : The coefficients in the expression are "8" and "15. The variables in the expression are "h" and "t". 

Part B: There are actually two terms in the expression and they are "8h" and "15t". Terms are separated by a plus sign or a minus sign.

Part C: "15t" is the term  in the expression that shows the total earned for tablets sold.
