Short answer. No it is not. A polynomial consists of more than 1 term which cannot be combined by either addition or subtraction. Actually most experts say that it must have more than 2 terms. So here is an example of a polynomial.
2x + 3y + 2z. You can't make this any simpler.
2x^3 + 3x^2 + 6x is also a polynomial. Don't get caught by saying it is not and that the terms can be combined in some way. They can't.
3x^2 + 7x^2 is not a polynomial. The x^2 are the same and therefore you can add the 3 and 7 together.
10x^2 is you answer.
1 km = 0.621371 miles
80 * 0.621371 = 49.7097 miles
which is about 50
therefore your answer is B: 50 miles

<h3>✒️ACCELERATION</h3>
=================================
Calculate the acceleration of riding her bicycle in a straight line that speeds up from 4 m/s to 12 m/s in 10 seconds.
=================================
=================================
Here we have a given of,
Because acceleration has a direction <u>(</u><u>riding her bicycle in a straight line</u><u>)</u>, it is important to always subtract the final velocity represented as 
from your initial velocity also represented as 
.
Now 'Work it out' and solve for Acceleration of riding her bicycle using the given formula.
Hence, The total acceleration of the girl riding her bicycle is 0.8 meters per second squared (m/s²).

In a direct variation relationship the values must satisfy that y = kx. This si y is always a constant value (k) times x.
So, you can find multiple values that meet this:
y = kx => k = y / x = 11 / 18
=> y = (11/18)x
Now you can give any value to x and fint the value of x that satisfy the relationship:
x y = (11/18)x
1 11/18
2 11/18 * 2 = 11/9
18 11/18 * 18 = 11
36 11/18 * 36 = 22
So, there you have several additional values for x and y in the same relationship that y = 11 and x = 18, and you can find many more using the same rule: y = (11/18)*x
