Option B is correct
because in a triangle the sum of the 2 sides must be greater than third side but in option B
12cm = 7cm+5cm
12cm = 12cm
hence it cannot form a triangle.
Answer:
x = 
Step-by-step explanation:
the ratio of side to hypotenuse in a right triangle is 1 : 
in this problem we can use 'x' in place of 1 and 
in place of to create a proportion like this:
1/x = /
cross-multiply to get:
·x =
x = 
x =
There would be 64 boys, 56/7=8 so you would have to multiple 8 by 8, which equals 64
If 1 of 25 is 101.6 ( 2540/25)
Then 23 is 2336.8 (23*101.6)
The Mississippi river is 2336.8 miles long
