Answer:
Step-by-step explanation:
It doesn't look right to me, but you may not have the choices I would want to use. I think it should go
1/2
cos^2
sqrt(x)
+ 2)
The square root covers just the x, and nothing more.
Answer:
3 - (x - 1) = 1/2(3x - 4)
Step-by-step explanation:
Since the dimensions are 40 ft by 60 ft, and 16 ft high, I assume the floor of the room is shaped like a rectangle.
Each wall is a rectangle. Two walls measure 40 ft by 16 ft, and two walls measure 60 ft by 16 ft.
lateral area = 40 ft * 16 ft * 2 + 60 ft * 16 ft * 2
lateral area = 1280 ft^2 + 1920 ft^2
lateral area = 3200 ft^2
15% = 0.15
<span>8 = 0.15x </span>
<span>8/0.15 = x </span>
<span>x = 53.33 or 160/3</span>
I’m pretty sure it’s 6 because you just need to add them together
