Answer:
By the Pythagoras theorem, the hypotenuse (c), is equivalent to:
a^2+ b^2= c^2 where a and b are the other two sides of the right angled triangle, hence c= square root (15^2+ 20^2)= 25
Answer:

Answer:
M and N
Step-by-step explanation:
2 shoes in each box * 19 shoe boxes = 38 shoes
38 shoes * 9 shipping boxes would be 342 shoes in all
A good estimate would be around 342. Hope that helps
You multiply 3x - y = 3.
So then it's:
6x - 2y = 3
-2x + 2y =6
which equals 4x = 9
