Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!

Answer:
10cm, 5cm, 7cm.
Step-by-step explanation:
So basically what I did was I pretended the line was a ruler that was in centemeters, and all the lines were centimeters, so then I added it up to get my answer, as you can see in the picture
That is a very good question
Look Wade...
If you faced it in the form (x^2+a)^0.5 , you would use the substitution of x=a*tan(y)
If you faced it in the form (x^2-a)^0.5 , you would use the substitution of x=a*sec(y)
If you faced it in the form (a-x^2)^0.5 , you would use the substitution of x=a*sin(y) or even x=a*cos(y)
It would be better if you provided an example ...
I am with you if you faced any difficulties!
