The third side of a triangle is between
the difference and sum of the other two
sides.
The number of integers from a to b,
inclusive is b – a + 1
y = ax2 + bx + c y – k = a(x – h)2
Sum = Average · Number
y = mx + b y = b x = a
Parallel lines: same slope.
Perpendicular lines: negative
reciprocal slopes
Total = X + Y – Both + Neither
distance = rate · time
