All you have to do is subtract 85 from 510 till you have 0
35000, rounding down from five.
Answer:
8
Step-by-step explanation:
For the smallest possible length, this has to be one of the shorter sides. Let the length of this side be x.
So, by the triangle inequality theorem, 1+x>8, which means x>7.
So, the smallest possible whole number length is 8.
b^2-4ac<0 b^2-144<0 (b-12)(b+12)<0
-12<b<12
We have an equation: 432/?= 3/5
Cross multiply:
3*?= 432*5
⇒ ?= 432*5/3= 720
