Robin can clean 72 rooms in 6 days. how many rooms can robin clean in 9 days?

108

Step-by-step explanation: Divide 72 by 6 and you should get 12. Then multiply 12 by 9 and you should get 108. It’s Easy!

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

i think it would be c
