$\\ \sf\dashrightarrow \dfrac{x+20}{2}=3x$

$\\ \sf\dashrightarrow x+20=2(3x)$

$\\ \sf\dashrightarrow x+20=6x$

$\\ \sf\dashrightarrow 20=6x-x$

$\\ \sf\dashrightarrow 5x=20$

$\\ \sf\dashrightarrow x=\dfrac{20}{5}$

$\\ \sf\dashrightarrow x=4$

Leading coefficient of the polynomial 4x^2−x^6+2x−6

ICE Princess25 [194]

Answer: The leading coefficient is -1.

Step-by-step explanation: Coefficients are the numbers than procede each term with a variable (in this instance,<em> </em>x) in the equation.

$-x^6+4x^2+2x-6\\$

There are four terms in this equation, which has been reordered in the correct form, which is from the highest term to the lowest term (based on exponent values).

Thus, there are three coefficients in this equation, which, in order, are as follows:

$-1, 4, 2$
