What two numbers add to 34 and multiply to -240

X+y=34
(x)(y)=-240
x=34-y
(34-y)(y)=-240
34y-y^2=-240
y^2-34y-240=0
(y-40)(y+6)=0
So the possible solutions of x and y is 40 and -6.

40, -6

Iagree that is the answer to the question

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
