1. Equivalent Expressions are written quantities that are equal.

To find equivalent expressions, it looks like you can just expand the second expression and then see if it matches the first.

2. So, expand 5(2x+3) using the distributive property.

5(2x+3) = 5×2x + 5×3 = 10x+15

It matches the first expression which means that they are equivalent.

I will also do 2-5 for you to check your work.

3. -2(-6+5) = 12-10 = 2            2 ≠ 12x-10

not equivalent

4. 3(4x+5) = 12x+15              12x+15 ≠ 12x-15  

not equivalent

5. -(-4x-3) = 4x+3                    4x+3 ≠ 4x-3

not equivalent

Add the following polynomials, then place the answer in the proper location on the grid. Write answer in descending powers of x.
CaHeK987 [17]

Answer:

-x^5+3x^4+16x^3+7x^2-3x+6

Step-by-step explanation:

Given polynomials are:

x^5-4x^4+7x^3+8, 9x^3+7x^2-10 and -2x^5+7x^4-3x+8

Now we need to add the given polynomials, then place the answer in the proper location on the grid. Also we need to write answer in descending powers of x.

So let's add them by combining like terms:

x^5-4x^4+7x^3+8+9x^3+7x^2-10-2x^5+7x^4-3x+8

-x^5+3x^4+16x^3+7x^2-3x+6

Hence final answer in descending order is -x^5+3x^4+16x^3+7x^2-3x+6
