Dividing and Multiplying functions

Likurg_2 [28]

Ok, so first of all, you need to plug the functions into their places. Since f(x) = 6x and g(x) = x + 3, you'll plug them in accordingly:
(6x) * (x + 3).

Then you'll multiply them together to get 6x^2 + 18x. You can't combine like terms then because of the square in the first term.

So your final answer is 6x^2 + 18x.

I hope this helps you at least a little bit. Thanks for your time!

Answer: 33.9

Reasoning: This is due to it just being tan(72) x 11 which would give you 33.8545... but using that you would just round it up to get 33.9

Answer:

The surface area of the prism is $1,664\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to

$SA=2B+PL$

where

B is the area of the triangular face

P is the perimeter of the triangular face

L is the length of the triangular prism

<em>Find the area of the triangular face B</em>

$B=\frac{1}{2}(24)(16)= 192\ mm^{2}$

<em>Find the perimeter of the triangular face P</em>

$P=(24+20+20)= 64\ mm$

we have

$L=20\ mm$

substitute the values

$SA=2(192)+(64)(20)=1,664\ mm^{2}$
