Answer:

No, it is not.

Step-by-step explanation:

This is because if you look at the expression, there is no term that is raised to the cube root. As a result, this isn't a cubic polynomial. However, this would be a quadratic polynomial cause the highest raised exponent is 2, which is the number for quadratic.

How do you solve this <br> 3(2.6x-3=4(-7-2.8)

Maslowich

Answer:

$x=-3.87$

Step-by-step explanation:

We want to solve for $x$ in $3(2.6x-3)=4(-7-2.8)$

We expand to get: $7.8x-9=-28-11.2$

We group similar terms to get:

$7.8x=9-28-11.2$

This simplifies to $7.8x=-30.2$

Divide both sides by 7.8 to get

$x=\frac{-30.2}{7.8}= -3.8718$
