(7+11) is 18, (8/2) is 4, 18-4 is 14! If this expression is 6 less than her age, she would be 20!
Hope this helps but I this helps but I think the answer is D if not then try B
Answer:
<u>x^3-8x^2+5x+14</u>
Step-by-step explanation:
(x+1)(x-2)(x-7)
x^3-8x^2+5x+14
A plot of residuals (vertical deviations from the regression line) shows the errors or lack of fit, so it would indicate a good fit if the residuals are small, vs. over fit if they are large. Due to age related growth short pre teen, and a plateau after age 21, I would expect a linear regression would offer estimate age 5.5 years.
X times 2x=50
2x^2=50
Divide by 2
X^2= 25
X=5
Length is 10 ft
