ANSWER
B) 15
EXPLANATION
The given polynomial is

We arrange this polynomial in ascending powers of x to obtain the standard form;

The degree of this polynomial is 6.
The coefficient of the leading term is 15
The answer is 5. Mode is the number that shows up the most times
Answer:
10
Step-by-step explanation:
Let us consider the distance between kensington and greenwich be x
since the given figure is a right angled triangle,we use pythagoras theorem to find the answer
so by pythagoras theorem
x^2= 20^2+40^2
x^2=400+1600
x^2=2000
x=root of 2000=20root 5mi
answer is option (b)
