Which polynomial represents the difference below? (8x^2 + 9) - (3x^2 + 2x + 5) a. 5x^2 - 2x + 4 b. 5x^2 - 2x + 14 c. 11x^2 - 2x + 4 d. 11x^2 + 2x + 14

Option a is the answer

The answer would be a.5x^2-2x+4 because you would distribute the negative which is -1 then combine like terms.

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
