Answer:
![-x^5+3x^4+16x^3+7x^2-3x+6](https://tex.z-dn.net/?f=-x%5E5%2B3x%5E4%2B16x%5E3%2B7x%5E2-3x%2B6)
Step-by-step explanation:
Given polynomials are:
,
and ![-2x^5+7x^4-3x+8](https://tex.z-dn.net/?f=-2x%5E5%2B7x%5E4-3x%2B8)
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](https://tex.z-dn.net/?f=x%5E5-4x%5E4%2B7x%5E3%2B8%2B9x%5E3%2B7x%5E2-10-2x%5E5%2B7x%5E4-3x%2B8)
![-x^5+3x^4+16x^3+7x^2-3x+6](https://tex.z-dn.net/?f=-x%5E5%2B3x%5E4%2B16x%5E3%2B7x%5E2-3x%2B6)
Hence final answer in descending order is ![-x^5+3x^4+16x^3+7x^2-3x+6](https://tex.z-dn.net/?f=-x%5E5%2B3x%5E4%2B16x%5E3%2B7x%5E2-3x%2B6)
Q is negative two thirds which is written as -2/3
Answer:
Step-by-step explanation:
Let price of milgrade gas be x and price of lawnmower gas be y.
18x + 5y=59.51
14x+y=39.75
Isolate one variable and substitute to solve for other variable.
Answer:
In a paragraph proof, statements and their justifications are written in sentences in a logical order.
A two-column proof consists of a list statements and the reasons the statements are true.
A paragraph proof is a two-column proof in sentence form.
Step-by-step explanation:
- In a paragraph proof, statements and their justifications are written in sentences in a logical order.
- A two-column proof consists of a list statements and the reasons the statements are true.
- A paragraph proof is a two-column proof in sentence form.
A paragraph proof is only a two-column proof written in sentences. However, since it is easier to leave steps out when writing a paragraph proof.
A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true. The statements are listed in a column on the left, and the reasons for which the statements can be made are listed in the right column
