Since there are as many of these triangles as the polygon has sides (eight for an octagon), you have to multiply the area of this triangle by the number of sides. You will obtain the total area of the octagon: area of octagon = 8 * base * height / 2 = perimeter * apothem / 2 .
i hope this helped you :)
The answer is g(x) = x^2 + 13x + 30
You can get this is multiple ways. Firstly, you could factor to find the zeroes and then move the answers to the left and redistribute the parenthesis.
You could also put the equation into vertex form and shift the number inside the parenthesis by 4.
Either will give you the exact same answer.
