Alright, so this is simple.
P= 50,000 or 50 thousands
G= 13 Tons
The variable f isn't known.
So your equation would be 13 = 50 (f), if you were to put your known variables in the equation.
If you were to find variable f, you would divide 13 tons by 50,000 to get 0.00026 or in scientific notation: 2.6 x 10 (exponent(s):-4)
F(x) = g(x) for x = 1 and x = 3. Verify that for yourself.
A = 1/2 bh
A = 1/2 (21)(8)
A = 1/2 (168)
A = 84
