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>

You have the value for y, so you substitute that equation for y, times three because there are three yS.
So you have: 2x + 3y = 10
2x + 3 x 2x + 4 or 2x + 3(3x + 4)
so the answer would be B, 2x + 3(3x + 4)
Absolute value of |2 1/2| is 2 1/2
Answer:
A

Step-by-step explanation:
According to the Factor Theorem, if (<em>x</em> - <em>k</em>) is a factor of a polynomial P(x), then P(k) must equal zero.
We are given that a polynomial function has the zeros 2, √3, and -√3. So, we can let <em>k</em> = 2, √3, -√3.
So, according to the Factor Theorem, P(2), P(√3) and P(-√3) must equal 0.
Testing each choice, we can see that only A is true:

Testing all three values yields that:

Hence, our answer is A.
