9x^2 + 18x + 9 = 5
9(x^2 + 2x +1) - 5 = 0
x^2 + 2x - 4 = 0
Then use the quadratic formula.
Answer: 8 members of the science group decided to watch the science fiction movie
Step-by-step explanation:
When a group of 40 friends goes to the movies at a multiplex, 1/5 of the group decides to watch a science friction movie. This means that the total sum of the members of the group that decided to watch the science fiction movie and the members that did not watch the science fiction movie is 40.
If 1/5 of the group decides to watch a science friction movie, that means that 1/5 of 40 watched the science fiction movie. It becomes
1/5 × 40/= 40/5 = 8
8 members of the science group decided to watch the science fiction movie.

Step-by-step explanation:
Call the full trip, x. Thus we can write 60% of x is 45, or .6x = 45 x = 45/.6 = 75 miles.
