The reason they have to be simplified is that you cannot add radical unless the number under the radical is the same on all of them.
For example:
If you add √8 + √32 without simplifying, the best you could do is an estimate. But if you're required to put your answer in standard radical form this would be an issue.
So, you would have to simplify to combine:
√4√2 + √16√2
2√2 + 4√2
6√2

Answer:
Deborah used 10 pages
104-16=89
89 divided by 9 is 9.89
so Deborah filled 9 full pages and 89% of a 10th page
therefore, she used 10 pages
Step-by-step explanation:
Length of DE = sqrt ( (-5- -3)^2 + (9-6)^2)) = sqrt 13
Length of the adjacent side EF = sqrt ( (-3- -6)^2 + (6 - -2)^2) = sqrt73
So its not a rhombus or a square.
Slope of DE = (9-6) / (-5 --3) = -3/2 and slope of EF = (6- -2) / (-3--6) = 8/3
these slope are not at right angles to each other
Therefore we haven't got a rectangle here.
Answer:- Parallelogram.
Answer:
.12 = 12/100 or 4/25 I'm not sure if I'm correct but I tried, I'll try solving the other ones and update you
.250 = 25/100 which simplified is 5/20
