Answer:
6.99 rounded up to 7 :))
Step-by-step explanation:
1/3 = 0.33
2.33 * 3 = 6.99 ft
Answer:
Correct option: C.
(Both Joey and Nolan)
Step-by-step explanation:
The step Joey did is:
Add 7x to both sides of the equation
Then, he got:
13x - 42 + 7x = 18 - 7x + 7x
20x - 42 = 18
The step Nolan did is:
Add 42 to both sides of the equation
Then, he got:
13x - 42 + 42 = 18 - 7x + 42
13x = 60 - 7x
So both of them used correctly the addition property of equality in the first step of their work.
Correct option: C.
Given:
The polynomial is

To find:
One term which is used to add in given polynomial to make it into a 22nd degree polynomial.
Solution:
Degree of a polynomial is the highest power of the variable.
Let,

Here, the highest power of x is 19, so degree of polynomial is 19.
To make it into a 22nd degree polynomial, we need to need a term having 22 as power of x.
We can add
, where k is constant.
So add
in the given polynomial.

Now, the degree of polynomial is 22.
Therefore, the required term is
.
