(4^9)^5 is equal to 4^45. You multiply 9 and 5 to get 45.
Answer: CD=18
Explanation: Use the side-splitter theorem and solve.
1) (3/x)=(4.5/(x+6)), cross multiply and solve for x
2) 6x+36=9x
3) x=12
4) Solve for CD
5) (12)+6=18
Subtract 5 each play so go backwards from zero and you should finish at -15
