Answer:
n=5/4 or n=-1/4
Step-by-step explanation:
16n^2 - 10n-5=6n
16n^2-16n-5=0
(4n)^2-2.4n.2+2^2 = 2^2 + 5
(4n- 2)^2=9
4n-2 = 3 or 4n-2=-3
4n=5 or 4n=-1
n=5/4 or n = - 1/4

Answer:
b. 61.75
Step-by-step explanation:
Split it into a rectangle and a triangle
1. Rectangle
You can see that the side lengths are 7 and 6.5, so the area is 7 * 6.5 = 45.5
2. Triangle
You know that the base is 6.5 and that the height is 5 (because 12 - 7 = 5) so you can find the area by doing 6.5 * 5 / 2 = 16.25
3. Total
Add the two areas, so 45.5 + 16.25 = 61.75
