Answer:

$5x^{2} -18x-8$

Step-by-step explanation:

The formula for area of a rectange is lw, where l is length and w is width. Since x-4 and 5x+2 are the sides, we can multiply them together to give us the area. We do (x-4)(5x+2). We use the FOIL method (First Outside Inside Last) and get 5x^2-18x-8.

2) Now solve 2x+x=18

Add alike terms

3x=18

Now divide both sides by 3 (3x/3 and 18/3)

x=6

Need help finding this answer

ch4aika [34]

Answer: Option 1

Step-by-step explanation:

1. You know the lenght of both rectangular prism, therefore if both are similar, the scale factor is:

$sf=\frac{12cm}{4cm}\\sf=3$

2. Then the scale factor of the volumes is:

$sf_v=3^{3}\\sf_v=27$

3. Now, you must multiply the volume of the smalller rectangular prism by the scale factor obtained, then you obtain the following result:

$V_2=(24cm^{3})(27)=648cm^{3}$

If f(x) = e^X, and W(f, g) = 3e^x, find g(x).

trasher [3.6K]

Answer:

g(x)=3

Step-by-step explanation:

Let's find the answer.

W(f,g)=3e^x which can be written as:

W(f,g)=(3)*(e^x), notice that:

(e^x)=f(x) so:

W(f,g)=3*f(x), establishing:

W(f,g)=g(x)*f(x) then:

g(x)=3

In conclusion, g(x)=3.
