What is the leading coefficient of the polynomial? 7x + 10x2 + 3x3 - 5 A) - 5 B) 10 C) 3 D) 7

The answer to your question is: 3, letter C

Step-by-step explanation:

Leading coefficient is the coefficient that is written in front of the variable with the highest power.

7x + 10x² + 3x³ - 5

In this polynomial the term with the highest power is 3, so the coefficient that is in front of the variable with this power is also 3.
