Answer:
x=3
Step-by-step explanation:
Because it is equilateral, all the sides are equal. so you can make your equation
3(2x-3)=21
Distribute the 3 throughout, giving you 6x-3=21
Subtract the 3 from both sides, and you are left with 6x=18
Divide 18 by 6 and you get 3.
Answer:
In this case, if you sum the first seven terms of your sum, you get 0.0002, that means that your error is less than 0.00002 , in other words, if you sum 6 terms of your sum, 4 terms of your result are correct, (because the error is less than 0.00002).
Step-by-step explanation:
Remember what the alternating series theorem says, basically it states that for a convergent alternating series .
The error of the series can be estimated as follows
The meaning of the theorem is that is an upper bound of the n-error of your sum.
In this case, if you sum the first seven terms of your sum, you get 0.0002, that means that your error is less than 0.00002 , in other words, if you sum 6 terms of your sum, 4 terms of your result are correct, (because the error is less than 0.00002).
49 is the answer cjfuvvryssokskdoxofo
60
Because 60 can be divided by all three of them, and it is the lowest one possible, 30 doesn't work because 30 divided by 12 is 2.5, and that isn't a whole number
6. If you take 216 and cube root it and you get six. and just to check you can do 6*6*6. 6*6=36 36*6=216.
Hope this helped!
