the product of two consecutive integers n and n+1 is 42. what is the positive integer that satisfies the situation?
MrMuchimi
n(n+1)=42 \\&#10;n^2+n=42 \\&#10;n^2+n-42=0 \\ \\&#10;a=1 \\ b=1 \\ c=-42 \\ b^2-4ac=1^2-4 \times 1 \times (-42)=1+168=169 \\ \\&#10;n=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-1 \pm \sqrt{169}}{2 \times 1}=\frac{-1 \pm 13}{2} \\&#10;n=\frac{-1 -13}{2} \ \lor \ n=\frac{-1+13}{2} \\&#10;n=\frac{-14}{2} \ \lor \ n=\frac{12}{2} \\&#10;n=-7 \ \lor \ n=6

The positive integer is 6.
The consecutive integers are 6 and 7.

This is the range of the addition of all 4 scores.

99+80+70=249

320-249= 71
356-249= 107

[71, 100] would be the answer, unless you can get extra credit on the final.
