2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.
Answer:
156.5375 cm
Step-by-step explanation:
The function used to estimate the height is F(x)
F(x) = 2.75x + 71.48
The humerus is xcm long. When x = 30.93cm, we put x = 30.93 into the function F(x)
F(30.93) = 2.75(30.93) + 71.48
= 85.0575 + 71.48
= 156.5375 cm(4 decimal places)
