P(x)=R(x)-C(x)
=(-0.5x²+800x-100)-(300x+250)
=-0.5x²+800x-100-300x-250
=-0.5x²+800x-300x-100-250
=-0.5x²+500x-350 (2)
The area of the triangle is 52.5 ft squared.

Step-by-step explanation:
Im not really sure if it's right
Do u still have this homework or is it old
Answer/Step-by-step explanation:
AC = 1.2
AB = 4
BC = 2.6
DF = 3
DE = 10
EF = 6.5
Thus:
The ratio of their corresponding sides are all equal to ⁵/2. Therefore, both triangles are similar.
