1. 0.625 and 62.5%
2. Match 1 had 156 expert fighters (0.5 x 312), Match 2 had 110 expert fighters (0.4x275) Match 1 had more expert fighters by 46
Rewrite then factor as a difference of cubes:
1 - 64<em>x</em>³ = 1³ - (4<em>x</em>)³
= (1 - 4<em>x</em>) (1² + 4<em>x</em> + (4<em>x</em>)²)
= (1 - 4<em>x</em>) (1 + 4<em>x</em> + 16<em>x</em>²)
6m + 15m+ 20= 75
6m+ 15m= 75- 20
21m= 55
m= 55/21
m= 2.61
