Which expressions are polynomial?
y
4x^3+y
2+s

which description is correct for the polynomial 4x^2+3x+5
cubic trinomial
quadratic trinomial

Polynomial means more than 1 term when all like terms are combined
terms are seperated by plus or minus symbols
you can't combine placeholders and numbers

y is 1 term, not poly
4x^3+y is 2 term, poly
2+s is 2 term, poly

answer is 4x^3+y and 2+s

cubic means highest power of the placeholder is 3
quadratic means highest power of placeholder is 2

trinomial means 3 terms

yep, 3 terms

4x^2+3x+5
highest power is 2
quadratic trinomial

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
