Answer:
2 x 2 = 4
Step-by-step explanation:
If you're trying to find the square root of say, 9, it would be 3 x 3 and your trying to find a square root something it's just something multiplied by itself again. such as the square root 1225 is 35 x 35, because 35 x 35 is 1225. Sorry if this is to complicated for you I learnt this in first term and I found it easy to grasp because of the way my math teacher taught it.
Sorry in advance ¯\_(⸟‸⸟)_/¯
X=-1
Trust me yurrrrrrrrrr
No it doesnt because it 8 is repeated and function has 1 outcome for each x
You would use 539 and square it on you cal. just once. Then once you do that the answer is not going to be a whole number it is going to have a decimal, so the answer would be 23.22.
2040 = n/2(20+(n-1)4)
4080 = n(20+4n-4)
4080= 20n +4n^2 -4n
1020 = 4n + n^2
n^2 +4n -1020 =0
use common formula (can't write out so just look at answers. sorry)
which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
