8 0

Answer:

  3p (2 square)- 2p-5

p (1-2)  2 (2-1)

(1-2) (p- 2 square)

Step-by-step explanation:

1/ see what numbers or letters have in common example: p we have two p's in the question we put p infront of the bracket and so on with the other and we remove the squares and then we group the umbers or letters

2/ and then we always put the common numbers or letters what was in the bracket together if it is not common then its wrong

3/ and the letters or numbers what is infront put them in a bracket also and there

understand or not

In a race between 18 people, how many ways can the top 5 finishers be arranged?
snow_lady [41]

Answer:

Step-by-step explanation:

This is permutation, since order matters.  The formula for us is

₁₈P₅ = \frac{18!}{(18-5)!} which simplifies to

₁₈P₅ = \frac{18*17*16*15*14*13!}{13!}

The factorial of 13 cancels out on the top and bottom leaving you with

₁₈P₅ = 18 × 17 × 16 × 15 × 14

which comes to 1,028,160 ways

Another way to look at it is:  the first 5 people of 18 finish and the others you don't care about.  Once the first place person is first, there are only 4 of the 18 left to finish in second place.  Then there are only 3 left to finish in third place, etc.  So if we use that reasoning, we don't even need to use the formula, we can just say

18 * 17 * 16 * 15 * 14 and those are the first 5 people of 18 to finish.

2(x-3)= 2x +5 help me out please
Igoryamba

Answer:

Look Down Low

Step-by-step explanation:

2(x - 3)  =  2x + 5

Multiply out the left side:

2x - 6  =  2x + 5

Subtract 2x from both sides:

   -6  =  5

Since this is impossible, this "equation" cannot be solved.
