Answer:

6x - 4

Step-by-step explanation:

Cross out the 3 in the denominator and the 9, which simplifies to 2 times 3x, which is 6x.  For the second part, cross out 3 in the denominator and -6, which becomes 2 times (-2), which is -4.

I need help with math.............
telo118 [61]
Greetings!

Solve using the properties of equality:
2(x+2)=4x+1-2x
Distribute the Parenthesis.
2x+4=4x+1-2x
Combine like terms.
2x+4=2x+1
There are no possible solutions.

Hope this helps.

Since they are similar you need to start by making ratios for each pentagon.
1.8/2.4 is the first and x/3.6 is the second. Now set them equal to each other and cross multiply.
1.8 X
___ = ____

2.4 3.6

2.4x= 6.48 Now divide both sides by 2.4

2.4x= 6.48
___ ____

2.4 2.4

X= 2.7

Let f(x) = x2 – 16 and g(x) = x + 4. Find fg f g and its domain.
Marta_Voda [28]

Answer: fg =x^3+4x^2-16x-64 and


Domain: All real number. All real number or (-\infty,\infty)



Explanation:


fg means product of two given function f(x) and g(x)


where,  

f(x)=x^2-16 and g(x)=x+4


Now, we have to find fg


So, fg=f(x)\times g(x)


Substitute f(x) and f(x)


\Rightarrow (x^2-16)(x+4)


Using distributive property simplify above expression and we get,  

\Rightarrow x^3+4x^2-16x-64


We can see it is cubic polynomial. So, domain of cubic polynomial is all real number.  

Domain: All real number or (-\infty,\infty)
