All of Sally's "likes" are squares: 225 = 15², 900 = 30², 144 = 12²

1600 = 40²

Sally "likes" 1600

B = √(14² - 9²) = √(196-81) = √115 ≈ 10.7 units

Let the number be x. Then 1.25x = 325, or x = 260.

20% less than 260 is 0.80(260) = 208

B is the answer

As x → ∞, f(x) → - ∞

As x → - ∞, f(x) → - ∞

They are equivalent because they have the same numbers and when you do the math it give 96 for both of them
