Answer:
Step-by-step explanation:
alright lets get started.
Please refer the diagram I have attached.
the runner traveled, six kilometers east.
Next, they turn to north and suppose they run x kilometers.
The starting and the ending points distance is 10 kilometers.
There will be a right triangle formed, we can find the value of x by using Pythagorean theorem.
Subtracting 36 from both sides
So, the runners travel 8 kilometers to the north. : answer
Hope it will help. :)
Whenever there's an interruption of say a sign like + or -, what's before it and after it is a "term", so for example,
a + b <---- two terms
a + b + c <---- three terms
25x⁻¹ - 17y² + 3 - 21x² <---- four terms.
the degree of a polynomial, is based on the exponents of the variables in each term, you add the exponents of the variables for that term, and the term with the highest degree, is the degree of the polynomial,
notice the polynomial here, it has 4 terms... what's its degree? let's check the degree of each term,
the term with the highest degree is the first one, with 12, and therefore, the degree of that polynomial is 12 then.
