A triangle has side lengths of 3m2 + In-2, -2m2 + 7m - 4n+ 5 and 8m2+n+ + 6m + 1. What is the perimeter of the triangle?
2:
a)
11m2 + m - 11n +6
b) 9m2 + m2 + 13m + 3n + 8
3:
c) None of these
d)
24m2 - 2n +42m - 28n-10
e) 11m2 - n° +13m + 3n+4

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
