The point A is translated to the point B by the vector (4u above 3u).

|AB| (with arrow on top of AB) = 12.5

I have seen people work this out by doing:

4u^2 + 3u^2 = 12.5^2

16u^2 + 9u^2 = 12.5^2

u = square root of 12.5^2/25

My question is: How do you know that you have to square 4u and 3u??

- Thanks!

You must find the surface of the block therefore 98187 dived by 5628 = 583m squared

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
