Being as their is no variable in your equation, the answer regardless of what we put in for the function is 7.
Step-by-step explanation:
f(x) = 2*2 + 3
f(x) = 4 + 3
f(x) = 7

Answer:
Angle made by ramp with ground is ≈
Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
Horizontal Distance of Skateboard ramp is 
 ft.
Height of Skateboard ramp is 
 ft.
From figure,
It is forming a Right angle triangle 
.
In 
, 
 and 
.
Clearly see that we need to find measure of angle 
.
Using Trigonometric ratio:
      
So,  
Then 
Therefore, Angle made by ramp with ground is ≈
