Answer:
Lesser x = ⅕
greater x = 4
Step-by-step explanation:
(x - 4)(-5x + 1) = 0
Write each factor separately
✔️(x - 4) = 0
x - 4 = 0
Add 4 to both sides
x = 4
✔️(-5x + 1) = 0
-5x + 1 = 0
Subtract 1 from each side
-5x = 0 - 1
-5x = -1
Divide both sides by -5
x = -1/-5
x = ⅕
✔️Lesser x = ⅕
greater x = 4
Number of ways of picking a smaller number out of a bigger number is called combination.
Number of way of picking 3 stamps out of 4 is 4C3 (4 combination 3) = 4! / (3! x (4 - 3)!) = 4! / (3! x 1!) = (4 x 3 x 2 x 1) / (3 x 2 x 1 x 1) = 24 / 6 = 4 ways.
