Answer:
-9 < r < -7
Step-by-step explanation:
9 + 3r < 2 + 2r
r < -7
-3 - 5r < 6 - 4r
-9 < r
r > -9
-9 < r < -7
The total number of shares owned by x shareholders
= x*y
=xy shares
The percentage of shares=
The three missing lengths are the left hypotenuse, x, the middle altitude, y, and the right hypotenuse, z.
9/y = y/16
y^2 = 9 * 16
y^2 = 144
y = 12
9^2 + 12^2 = x^2
x^2 = 225
x = 15
12^2 + 16^2 = z^2
z^2 = 400
z = 20
From left to right, the sides measure 15, 12, and 20 units.
