So for the triangle you would use the formula A= 1/2 bh (b represents the measurement of the base, h represents the height)
A= 1/2 30(40)
A= 1/2 1200
A=600
Now for the rectangle you use the formula A= l x w (l represents length, w means width)
A= 100 x 40
A= 4000
Now you just add the two answers together
A= 4000 + 600= 4600
so we have 16=4(9-x) we calculate this equation
16=(4*9)_x*4
so 16=36-4x
wich means these 2 equations are equivalent
If the car is traveling at 36ft/s per converted mph divide the amount of travel length the person will travel and subtract is by 1 this being the second tracked which is 36ft/s
Answer:
22.470
Step-by-step explanation:
In this example you have to use the trigonometric function sine which is defined as 
Plug in known values:
Multiply both sides by 25
Approximate sin(64) using a calculator:

Hello!
First, "the difference" of 2 numbers means you subtract these numbers.
Then, 4 cubed is written as follows:
4³
Subtract:
4³-25
[If necessary] Evaluate:
64-25
39
Hope everything is clear.
