2 For every 1 litre of water used to make a medicine, 17ml of sucrose
and 29ml of saline solution are used. Express the amount of water,
sucrose and saline solution needed as a ratio in its simplest form.

pretty sure 750 each month!

step-by-step explanation:

i think the length is 12 and the width is 17

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
