everything except the last two, I think.
Cos = adjacent / hypotenuse
cos B = 4/5
B = cos^-1 (4/5)
B = 36.869897....
B = 36.87° (nearest hundredth)
Angle B = 36.87°.

Answer:
it's ax+b form answer is Q(x-2)=4x-6
Step-by-step explanation:
ax+b=Q(x),Q(x-2)=a(x-2)+2
Q(3x)=a(3x)+b=12x+2, 3a=12 =>a=4,b=2
the original q of x is 4x+2
Q of x-2 =4(x-2)+2=4x-8+2=4x-6
