Answer:
Hi there!
The correct answer is: (x+8)² = 73
Step-by-step explanation:
First you want to modify the equation: x² + 16x - 6 = 3 into x² + 16x = 9 by adding 6 on both sides.
Then you analyze the new equation, if you can see, 16x is positive which means two positive numbers have to be added up to equal a positive. Which eliminates the choices that have (x-8)²
And now you are left with two choices:
(x+8)² =73 and (x+8)² = -55
Now remember, when you factor out (x+8)² it equals to x² + 16x + 64
next let's bring it back to the very first equation: x² + 16x = 9
now which choice matches the result x² + 16x = 9. The answer will be (x+8)² = 73 because when you subtract 64 on both sides you get 9.
The area of the roof is 1984 sq. ft. 1984 square feet of roofing is needed for the roof of a building that is 32 ft wide and 62 ft long.
Given, the length of the roof is 62 ft long and the width of the roof is 32 ft wide. Therefore, the area of the roof is length * width.
Area of the roof = length of the roof * width of the roof
Area = 62 ft * 32 ft
Area = 1984 sq. ft
Here, also given the slope of the roof is 1:2 which indicates the ratio of rise and run.
Slope of the roof = Rise / Run = 1 / 2
Then, the slope factor is 
= 
= 0.04167

The right question is:
How many square feet of roofing is needed for the roof of a building that is 32 ft wide and 62 ft long?
The table of values corresponding to the linear function that goes through (0, -2) and (2,0) is has points (x,y) in the following format:
(x, x - 2).
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
The line goes through (0,-2), hence the y-intercept is b = -2. The slope is given by:
m = (0 - (-2))/(2 - 0) = 2/2 = 1.
Hence the equation is:
y = x - 2.
Thus the points on the table are related as follows:
(x, x - 2).
For example
x f(x)
0 -2
1 -1
2 0
3 1
4 2
5 3
