Answer:
The difference between combinations and permutations is that in permutations, the order matters, while it doesn't with combinations. For example, if you are given 5 numbers (1,2,3,4,5) and you have to determine how many 3 digit numbers you can make, that is a permutation question because 123, 231, 321, etc. are all different numbers. If, for example, we have to find how many ways three people can be chosen out of a group of 5, that is a combination question and you must use the combination formula as the order of the three people does not matter. Other than the order, combinations and permutations are the same
Answer:
2.3,7,127
Step-by-step explanation:
a₁ = 2
a₂ = 2² - 1 = 3
a₃ = 2³ - 1 = 7
a₄ = 2⁷ - 1 = 127
4x+4 you have to distribute it
I believe that the answer to this question would be 2(12a + b^3). Wait for someone else for clarification. :)
Answer:
1 ft^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
A = 1/2 ( 3) * ( 2/3)
A = 3/2* 2/3
A =1
