How many different ways are there to arrange the letters a, b, a, and b? 4 6 8 16

There are 6 different possible arrangements of letters A, B, A, B.

Solution:

Need to determine different ways to range letters A, B, A and B.

Using the theorem which says that the number of permutation of n alphabets, where number of alphabets of one kind and is number of alphabets of second kind is given by following formula.

Number of possible arrangements

In our case total number of alphabets = n = 4

Number of letter A = = 2

Number of letter B = = 2

Using (1), we get

Number of possible arrangements of A, B, A, B

Hence there are 6 different possible arrangements of letters A, B, A, B.

Your answer would be: 6 (six)

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
