Answer: -4/1
Step-by-step explanation:
Answer:
144(3/4)^1-n
Step-by-step explanation:
This is a geometric sequence, so if you divide 192 by 144 you will find that the common ratio r is 4/3. This would make the equation an=144(4/3)^n-1. However, that's not one of the options. If you plug in some numbers, you can see that 3/4 (the reciprocal of 4/3) can work as well if it's 3/4^1-n. 4/3^-1=3/4 and n-1(-1)=1-n
The answer I think it’s Y=(3-x)(x+8)
Answer:
Y = 168°
X = 12°
Step-by-step explanation:
Y = 168 degrees
X = 5x -48
48 = 4x
12 = x
