Step-by-step explanation:
Answer:
It is 20m.
Step-by-step explanation:
The perimeter equals the sum of all the sides. So 5+7+3+4+1
If it's x²y³ then we know it's the second term of the expansion, that known we can use the combination
C(5, 2) = 5!/(2!.3!) = 10
Then if we had something like
(a + b)^5 our second term would be 10a²b³ but as we can see it's "a²"
And in our case we have 2x as a
So we must do 2² too
2² = 4
10 . 4 = 40
Then our second term of the expansion would be
40x²y³
A number is divisible by two if you get no remainder when you divide that number by two. Even numbers are divisible by two. Odd numbers are not divisible by two.
Answer:
It would have taken 12day for 6person to build 12 computers
Step-by-step explanation:
Since
4person = 18days
1person = 4 x 18 = 72days
Therefore if two more person helped
4person + 2 person = 6person
6person = 72/6 = 12days
It would have taken 12day for 6person to build 12 computers
