3+8+10+14+11= 46
46/(how many trees) 5= 9.2
9.2 years is your answer.
I think its 6 cm for the 3rd side
10/15 =6/9
6*15=90
90/9=10, this is how I found 10,
also, is you simplify both, you get 2/3
-x - x - 3x - 4x
Let's start from left to right. First do -x - x, which is -2x.
-2x - 3x - 4x
Now do -2x - 3x, which is -5x.
-5x - 4x = -9x
-9x is your answer.
