Answer:
174 centimeters
Step-by-step explanation:
You take 150 and divide it by 10 which gives you 15. since you divide it by 10 and it gives you 15 that means ten percent is 15 centimeters. since we need to find out what the 16 percent is we take the 15 and divide that by 10 which gives us 1.5. That tells us every 1 percent, is 1.5 centimeters. you take the 150 and add 15 and that gives you 165. We have already done 10 percent out of the 16 percent . Now we have to figure out how much the rest of the 6 percent is so we take the 1.5 and multiply it with the 6 and we get a 9. That covers up for the rest of the 6 percent out of the 16 percent. Now we add 165 with 9 to get our answer of 174 centimeters.

Step by step explanation:
9
+6x+5=0
Uses the "a", "b", and "c" from "a + bx + c", where "a", "b", and "c" are numbers
So in this case:
a would be 9
b would be 6
c would be 5
Then plug in from there..
Another way you can do it is using the square method.
