Answer:x^2-y^2
Step-by-step explanation:
(x+y)(x-y) = x^2 -xy +xy -y^2 so it becomes x^2-y^2

Answer:
<em>He drank 0.5 liters</em>
Step-by-step explanation:
1.5 - 0.25 = 1.25 liters
1.25 x 40% = 0.5
Answer:
Step-by-step explanation:
Since the coordinates of P are (0, 1), this makes P the y-intercept of that line. The y-intercept exists where x = 0. And in the coordinate (0, 1), x does in fact equal 0.
Since the one coordinate given in Q is (?, 0), this means that Q is the x-intercept of the line. The x-intercept exists where y = 0. And in the coordinate (?, 0), y does in fact equal 0. So in order to solve for the x coordinate of Q, we plug in a 0 for y and solve for x:
3(0) - 4x = 12 and
-4x = 12 so
x = -3
