22

Step-by-step explanation:

This is the answer because if you work backwards then number minus five is actually 9-5, so you're left with 4. And then you need to do 6 times he difference of 9-5, which is 4. So, 6 X 4 would equal 24. And then you need to do 2 less than that answer. So 24-2 would equal 22.  

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
