Answer:

2x+8

Step-by-step explanation:

Here, you have to find the similar sides. x and x are both the same thing, while 3 and 5 are both integers (whole numbers).

You add the similar sides together, then that is your answer.

x + x= 2x, and 3+5= 8.

Note: Just because I said that x and x are the same doesn't mean that you can just add random numbers together in other questions.

A fair coin is tossed .if the coin is tails one die is rolled and the number on the die is recorded if the coin toss is heads tw

svp [43]

So for the dice to be 9 two die must be rolled. So we start with a 1/2 chance.

Then there are 36 possibilities to be rolled on a die (6*6) and there are 4/36 possibilities for the dice to roll a 9 (4+5, 5+4, 3+6, 6+3).

So we multiply 1/2 by 1/9 (4/36)- which equals 1/18.

So there is a 1/18 chance for the result of the dice rolled to be a 9.

I hope this helps!
