F(X) means the function of X. So we just plug in 12 for X.
(3/4(12))+5/6=36/4+5/6=9+5/6=59/6
Answer:
25.75
Step-by-step explanation:
A hexagon has 6 sides so
6(4x + 30) = 798
distribute
24x +180 = 798
take away 180 from both sides
24x = 618
divide 24 both sides to get the variable by itself
<u><em>X = 25.75</em></u>

The answer you’re looking for is x=145.
Every circle adds up to 360 degrees. The only measurement that we know is 70, but the congruent markings tell us that the unknown “sides” are the same. Therefore, you’d take 360-70=290. There are 290 degrees around the unknown part of the circle, which we then divide by 2 to get 145 degrees total. I hope this helped, let me know if I can explain anymore:)
