Hello!
To solve this, first perform the opposite operation for the last operation (on the left side) on both sides. The last operation of the left side is squaring. Therefore, square root both sides.
Please note that you must include ±. This is because the square root of 64 can be either positive or negative, as a square of either a positive or negative number is positive.
Now, add 9 to both sides.
There are 2 solutions from here. One comes from adding 8, and the other subtracting 8. Therefore, the two solutions are:
y = 9 + 8 = 17
y = 9 - 8 = 1
Therefore, your two solutions are 17 and 1.
Hope this helps!

Terminate because 17/25 is the same as 68/100 and that is 0.68. So, it is terminate
Answer:
So, the probability is P=0.041.
Step-by-step explanation:
We know that 45% of people in Fast-Food restaurants order a diet drink with their lunch.
We conclude that the probaility p=0.45 that a person order a diet drink.
We calculate the probability that the fourth person orders a diet drink.
We get:
So, the probability is P=0.041.
