I think that inches would be most common for height but centimeters and feet could also be used.

A ball is thrown into the air. The height h, in feet, of the ball after x seconds is given by the function h = −16(x − 2)2 + 72.
Annette [7]

Answer:

Step-by-step explanation:

h = −16(x − 2)² + 72

 =  −16((x − 2)(x − 2)) + 72                   expand the square  (x - 2)² =  (x - 2)(x - x)

 =  -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72

  = -16 (x² + (-2x) + (-2x) + (4) ) + 72

  = -16 (x² + (-4x)  + (4) ) + 72

  = -16 (x² - 4x  + 4 ) + 72

  = (-16)(x²) + (-16)(-4x) +(-16)(4) + 72

  =   -16x²  + 64x  - 64 + 72

  =   -16x²  + 64x  + 8              My guess is D   ; 72 ???

I have no clue what the  ; 72 means after the given answer.  It must be a standard form thing I never learned.

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

x = 42

»»————- ★ ————-««  

Here’s why:  

  • We will use inverse operations to solve for 'x'.

⸻⸻⸻⸻

\boxed{\text{Calculating the Answer....}}\\\\3x+54=180\\----------\\\rightarrow 3x + 54 - 54 = 180-54\\\\\rightarrow 3x = 126\\\\\rightarrow\frac{3x=126}{3}\\\\\rightarrow\boxed{x=42}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
