Answer:
Step-by-step explanation:
-5/3 + -5/4
-50/12 + -15/12 = -65/12 = -5 5/12
Answer: you forgot attachment
Step-by-step explanation:
Answer:
Below
Step-by-step explanation:
Let x be that missing number
One third of it is x/3
One-ninth of it is x/9
Multiply x/3 and x/9
● (x/3)*(x/9) = (x^2/27)
● (x^2/27) = 108
Multiply both sides by 27
● (x^2/27)*27 = 108*27
● x^2 = 2916
● x = √(2,916) or x = -√(2,916)
● x = 54 or x = -54
So there are two possibilities 54 and -54.
Answer:
and 
Step-by-step explanation:
An algebraic expression is a polynomial if and only if the variables involve have positive integral indices or exponents.
The given polynomial is: 
We want to put one of the following polynomials in the blank space to create a fully simplified polynomial written in standard form.





A fully simplified polynomial written in standard form is obtained by writing the simplified polynomial in decreasing order according to degree.
Since the first term of
having a degree of 5 and the last term is having a degree of 3.
The polynomial that goes into the blank must have a degree of 4.
This eliminates
, 
and 
We are now left with
and 
The required polynomial is therefore
or
These two polynomials are in standard form and cannot be simplified further.
The correct choices are;
and
