Answer:
15
Step-by-step explanation:
Plug in 3 as x:
3x + 6
3(3) + 6
9 + 6
= 15
So, the simplified expression if x = 3 is 15
<h3>
sin22° = 5/4</h3><h3>
tan22° = 3/√55</h3>
As we know that , sinA = opposite/hypotenuse & tanA = opposite/adjacent
So here we can find sin22° , because they already given the sides opposite & hypotenuse . And we can't find tann22° because they given the value of opposite but not given the value of adjacent side of the angle 22°
Now finding the adjacent side using
Pythagoras theorem :-
• Hypotenuse² = Base² + Height²
=> 40² = Base² + 15²
=> 1600 - 225 = Base²
=> Base² = 1375
=> Base = √1375
=> Base = 5√55
Now ,
- tan22° = Opposite/Adjacent = 15/5√55 = 3/√55
- sin22° = Opposite/hypotenuse = 15/40 = 5/4

3 3
They only have 3 and two in common when you fully factor them. 3×2= 6
6 is the greatest common factor.

-4 because when you did use 12 divided by 3 you get four but this is negative so you get a negative answer
