Answer: 8
Step-by-step explanation: the given expression is 2n-3
so when n=1, we will get, 2(1)-3=2-3=-1
when n=2, we will get, 2(2)-3= 4-3=-1
when n=3, we will get 2(3)-3= 6-3=3
when n=4, we will get 2(4)-3 = 8-3=5
so the required result of expansion is -1+1+3+5=8
answer is 8.
hope that helped!

Step-by-step explanation:
I think it work
BLUF: ANS=4.0 ft^2
Arch = Rect - (Sector - Triangle)
rect = 5.7*1.5
Sector = pi r^2 /4
= 4pi
triangle = BH /2
