A = 15 a = athena, s = samantha, b = bonus points
s = b + a
s = b + 15
So 70 miles per hour is 70 mile/1hour
1 mile=5280 feet
70 tmes 5280=feet=36,960
so 36,960 feet per hour
Assuming that the equation is 3x^2+3x-6=0, then use the quadratic equation, (-b+- sqrt(b^2-4ac))/2a, with ax^2+bx+c as the original equation. so here we get (-3+-sqrt(9+72))/6 = (-3+-sqrt(81))/6 = (-3+-9)/6, = (-1+-3)/2 = 1 or -2. Plug in original to check.
T - 7 < 10, T = 28
28 - 7 < 10
21 < 10
FALSE
