Answer:
x = -9
Step-by-step explanation:
6x + 6 = 3x – 21
Subtract 3x from each side
6x-3x + 6 = 3x-3x – 21
3x+6 = -21
Subtract 6 from each side
3x+6-6 = -21-6
3x = -27
Divide by 3
3x/3 = -27/3
x = -9

6928ft
59.0813m
26 1/4m
Step-by-step explanation:
Area of a trapezoid = (a+b)*h/2 so (100+150)*80/2
= 10000
Area of a rectangle = l*w so 48*64
=3072
10000-3072 = 6928
The surface area of a square pyramid is A=a^2+2a√a^2/4+h^2 which is A=4^2+2(4)√(4)^2/4+(5)^2 which = 59.08
Volume of a rectangular prism is l*w*h so 3.5*1.25*6 = 26.25 which is equal to 26 1/4

Answer:
10 meters
Step-by-step explanation:
The given function 
represents the height, 
, in meters, 
seconds after the ball is thrown.
Since the ball is thrown off the roof, then ball's height will be equal to the roof's height before being thrown (0 seconds). Therefore, substitute 
into the given function :
Therefore, the building is 10 meters tall.
