If t=-3 (hopefully it does) then it's 6+-12/10. This is -6/10=-3/5
(0,-4) is the coordinate for point D
Answer:
4(3 + 2x)(-3 + 2x)
Step-by-step explanation:
The ratio is common, so you could write:
a1 * r^4 = a^5 (you do r^4 because there are 4 times you need to multiply by the ratio to get from a1 to a5)
Plug in the values:
3 * r^4 = 48
Divide by 3:
r^4 = 16
Take the fourth root of both sides:
r = 2
The common ratio is 2.
