Question 329424: Area of a sail. The area in square meters for a triangular
sail is given by A(x)=x^2+5x+6.
a) Find A(5).
b) If the height of the sail is x+3 meters, then what is
the length of the base of the sail?
Answer by nyc_function(2741) (Show Source): You can put this solution on YOUR website!
For part (a), replace every x that you see with 5 and simplify the function.
For part(b), A(x) = 1/2 times b time h, where A(x) = A(5), and h = x + 3.
Can you take it from here?
