Step-by-step explanation:
2(x+4) = 12
or, 2x + 8 = 12
or, 2x = 12-8
or, 2x = 4
or, x = 4÷2
hence, x = 2
Answer:


Step-by-step explanation:
We know the definition of both functions:
, and 
A) In order to evaluate what
, let's first investigate what g(-1) is using the definition for this function:

Now let's find what f(2) is using f(x) definition: 
B) In order to evaluate what
, let's first investigate what f(3) is using the definition for this function:

Now let's find what g(7) is using the definition for this function:

The equation which is equivalent to 60% of 25 is x = 0.6 * 25
An equation is used to show the relationship between variables, numbers.
Let x represent the value of 60% of 25. Hence:
x = 60% of 25
x = 0.6 * 25
Hence the equation which is equivalent to 60% of 25 is x = 0.6 * 25
x/25 = 60/100
6/10 = x/25
Its dedpool!
the answer here is B!
hope this helps!
