Sagot :

Answer:

Step-by-step explanation:

Prime numbers are : 31 , 83 , 71 , 17

31 + 83 + 71 + 17 = 202

Answer:

202

Step-by-step explanation:

Because we are adding prime numbers.

Our prime numbers are 31, 83, 71 and 17 Because prime numbers are numbers that don't have 1 factor regarding 1 so nothing can go into 31,81,71 or 17.

45 does have a factor and that is 9 and 5.

56 has 9 x 5   28 x 2   14 x 4  

So like I said we will now add 31,83,71 and 17

SO 83 + 17=100

100 + 31=131     131 + 71=202 and there is all your answers.

Hope this helps have a awsome day:)
