Answer:

−2x4−18x3y

Step-by-step explanation:

Let's simplify step-by-step.

(−3x2)(xy+2x2)+7x4−3x3(5y+x)

Distribute:

=(−3x2)(xy)+(−3x2)(2x2)+7x4+−3x4+−15x3y

=−3x3y+−6x4+7x4+−3x4+−15x3y

Combine Like Terms:

=−3x3y+−6x4+7x4+−3x4+−15x3y

=(−6x4+7x4+−3x4)+(−3x3y+−15x3y)

=−2x4+−18x3y

Answer:

$q = 16 \sqrt{2}$ and $r = 16$

Step-by-step explanation:

We know that

$\sin( \alpha ) = \frac{side \: opposite \: to \: \alpha }{hypotenuse \: of \: triangle}$
$\cos( \alpha ) = \frac{side \: adjacent \: to \: \alpha }{hypotenuse \: of \: traingle}$
$\tan( \alpha ) = \frac{side \: opposite \: to \: \alpha }{side \: adjacent \: to \: \alpha }$
