The answer is 34.05
The total distance (D) is the sum of three distances (d1, d2, and d3).
The distance formula is
Distance 1: Phoenix (–12, –16) to Blythe (–20, –9)<span>:
</span>
Distance 2: Blythe (–20, –9) to Los Angeles (–33, –4):
Distance 3: Los Angeles (–33, –4) to <span>San Francisco (–36, 5)
</span>
<span>
D = d1 + d2 + d3 = 10.63 + 13.93 + 9.49 = 34.05</span>

Option a:
Option b:
Option c:
Explanation:
The highest degree of a polynomial is the largest exponent of that variable.
Now, we shall determine the polynomial with degree 3.
Option a:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option a is the correct answer.
Option b:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option b is the correct answer.
Option c:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option c is the correct answer.
Option d:
From the expression , the highest degree of the polynomial is 1.
Hence, is a polynomial with degree 1.
Hence, Option d is not the correct answer.
