Answer:

The constant of proportionality is 6

Step-by-step explanation:

Recall the equation for direct variation is $y=kx$ where $y$ varies directly with $x$ and $k$ is the constant of proportionality. If we take any listed coordinate point, we can determine the value of $k$ . I will use (20,120) as an example:

$y=kx\\\\120=k(20)\\\\6=k$

Therefore, the constant of proportionality is 6

Expand.<br> Your answer should be a polynomial in standard form.<br> (3c + 2)(c^2-6c-4)

evablogger [386]

Answer:

After expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$

Step-by-step explanation:

We need to expand the polynomial $(3c + 2)(c^2-6c-4)$

Multiply the terms:

$(3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8$

So, after expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$
