Step-by-step explanation:

Should be right

Step-by-step explanation:

Let side be x

Using Pythagoras theorem

diagonal =hypotenuse

x²+x²=20²

2x²=400

x²=200

x=10√2

Side is 10√2

Perimeter=4×10√2=>40√2cm

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
