The value of x is equal to -5/6
To solve this question, we have to add two polynomials together. The polynomials are;
<h3>Addition of Polynomials</h3>
This involves adding of two or more different polynomials together. The polynomials adding together are or must be of the same degree. i.e x^2 must add to another coefficient of x^2 and x^3 adds to another coefficient of x^3 and so on.
In this given question, let's add the polynomials together.
Now, let's equate this with the last polynomial given
Let's solve for x

Answer: 0.82 miles per gallon
Step-by-step explanation:
Given : Jenna has bought a new hybrid car. Each week for a period of seven weeks, she has noted the fuel efficiency (x) (in miles per gallon) of her car.
The results are :45 44 43 44 45 44 43
The formula to find the standard deviation is given by :-
First we find mean of the given data ,
Now,
Now, standard deviation of the above results will be :-
Hence, the standard deviation of these results = 0.82 miles per gallon
Answer:
x + 4 = 47
x = 43
Step-by-step explanation:
i minus 4 from 47 to get x by its self and x = 43 do he was 43 inches last year
An absolute value equation which could represent the length of a plane is : 12 feets ≥ x ≤ 302 feets
Smallest length of a plane = 12 feets
Longest length of a plane = 302 feets
This means that the minimum length of a plane cannot be below 12 feets and the maximum length of a plane cannot be above 302 feets
Using x as the length of a plane :
To represent as an absolute value ; we use inequality :
Minimum length ≥ x ≤ maximum length
12 feets ≥ x ≤ 302 feets .
