Find the Leading Coefficient 3*4+5y

$3 \cdot 4 + 5 y$

Step 1

Simplify the polynomial, then reorder it left to right starting with the highest degree term.

Multiply $3$ by $4$ .

$12 + 5 y$

Reorder $12$ and $5 y$ .

$5 y + 12$

Step 2

The leading term in a polynomial is the term with the highest degree.

$5 y$

Step 3

The leading coefficient in a polynomial is the coefficient of the leading term.

$5$
