(9x^2+17x+13)−(2x^2+12x+11) simplifies to 7x^2+5x+2.

To multiply the polynomials (3x - 1)(2x + 4), you need to use the distributive property.

(3x - 1)(2x + 4) can be expanded as follows:

= 3x(2x) + 3x(4) - 1(2x) - 1(4)
= 6x^2 + 12x - 2x - 4
= 6x^2 + 10x - 4

Therefore, (3x - 1)(2x + 4) simplifies to 6x^2 + 10x - 4.

Expression 1: 22r - 13
Expression 2: 19r + (3r - 2) - 11

The associative property states that you can change the grouping of terms when adding or subtracting without changing the result.

Let's apply the associative property to Expression 2 by rearranging the grouping of terms:

19r + (3r - 2) - 11

We can first group the terms within the parentheses:

(19r + 3r - 2) - 11

Now let's combine like terms within the parentheses:

(22r - 2) - 11

Finally, let's combine the two terms outside of the parentheses:

22r - 2 - 11

Simplifying further:

22r - 13

We can see that Expression 2, after applying the associative property, simplifies to Expression 1. Therefore, Expression 1 is equivalent to Expression 2.

Expression 1: (x - 5)(x + 3)
Expression 2: 2x^2 - x^2 - 2x - 20 + 5

To prove that these expressions are equivalent, we need to show that the result is the same when we multiply them out.

Using the distributive property, we can expand Expression 1:

(x - 5)(x + 3) = x(x) + x(3) - 5(x) - 5(3) = x^2 + 3x - 5x - 15 = x^2 - 2x - 15

Simplifying, we have x^2 - 2x - 15.

Comparing this to Expression 2, we can see that both expressions have the same resulting algebraic expression: x^2 - 2x - 15.

Therefore, we have demonstrated that Expression 1 is equivalent to Expression 2, as they both simplify to the same algebraic expression x^2 - 2x - 15.

You are right, I apologize for the error. Let's correct the explanation.

Expression 1: (x - 5)(x + 3)
Expression 2: 2x^2 - x^2 - 2x - 20 + 5

Using the distributive property, we can expand Expression 1:

(x - 5)(x + 3) = x(x) + x(3) - 5(x) - 5(3) = x^2 + 3x - 5x - 15 = x^2 - 2x - 15

So the expanded form of Expression 1 is x^2 - 2x - 15.

Comparing this to Expression 2, we can see that Expression 2 is also equal to x^2 - 2x - 15.

Therefore, we have demonstrated that Expression 1 is equivalent to Expression 2, as they both simplify to the same algebraic expression x^2 - 2x - 15.
