Dexter has four different coins in his pocket. He randomly selects a coin from his pocket, replaces it, and selects another coin
skad [1K]

Answer:

Step-by-step explanation:

So what is the probability of the selecting the first coin? There are total of 4 different coins, so the probability of getting a dime is 1 out of 4, then he replace it, then again the probability stays the same, he still has 1 out 4 chance of getting a dime. So then it's just 1/4*1/4=1/16 :)

2 (-X + 3) + x <br><br> Ⓘ ⓡⓔⓐⓛⓛⓨ ⓓⓞⓝ'ⓣ ⓤⓝⓓⓔⓡⓢⓣⓐⓝⓓ
Darina [25.2K]

Answer:

  -x +6

Step-by-step explanation:

We assume you want to simplify this.

Use the distributive property to eliminate the parentheses. That property tells you that the factor outside parentheses (2) will multiply both of the terms inside parentheses. It's as though you had a bag (parentheses) with two objects inside. Two such bags will have two of each of those objects.

  2(-x +3) +x

  = 2(-x) +2(3) +x

  = -2x +6 +x

Now, the like terms -2x and +x can be combined.

  = x(-2 +1) +6

  = x(-1) +6

  = -x +6 . . . . . the simplified expression
