You are supposed to use the third option: 3n2 + 6n + 5 = 116.
Take a look at the attachment to see how I got that solution.
Hope it helps! :)
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
Area =

where p and q are it's diagonal
so according to the rule.



is the answer.

Answer:
A person who watches 8.5 hours of TV can do 30.4 sit ups.
Step-by-step explanation:
The regression equation is used to predict or estimate the value of the response (or dependent) variables using the information about the explanatory (or predictor) variables.
The general form of a regression equation is:

Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>a</em> = intercept
<em>b</em> = slope
The regression equation representing the relationship between hours of TV watched per day (<em>x</em>) and number of sit ups a person can do (<em>y</em>) is:

Compute the number of sit ups a person who watches 8.5 hours of TV can do as follows:


Thus, a person who watches 8.5 hours of TV can do 30.4 sit ups.
