Answer + ! what is the value of 3x^2 - 5xy + 5y^2 for x = -6 and y = 2? a. -68 b. -4 c. 188 d. 208

If you put in x for -6 and y for 2, you get 3(-6)^2 - 5(-6)(2) + 5(2)^2. 

Simplifying all the numbers, it's 3(36) + 30(2) + 5(4), and then 108+60+20. Going along, you get 188

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
