4x^2+4x-8=0
X^2+x-2=0
(X+2)(x-1)=0
X= -2 or 1
Answer: 1863m
69x31....2,139
12x23....276
2,139-276.....1,863
Hope this helped :)
5m/8 = 12
8 x 12 = 5m
96 = 5m
m = 96/5
= 19.2
1. Consider a triangle with sides a, b and c.
2. a, b and c can be sides of a triangle only if each of these conditions hold:
i) a+b>c
ii) b+c>a
and iii)a+c>b
3. So the only condition for 3 numbers to be the side lengths of a triangle is that the sum of any 2 of them must be larger than the third number
4. This is called the "triangle inequality".
