Answer:
5x²-7x+2
step by step explanation:
(f•g)(x) = f(x)•g(x)
(x-1)•(5x-2)
x×5x-2x-5x-1×(-2)
5x²-2x-5x+2
=5x²-7x+2
In this We need one more side congruent because one is common i.e FG. It is the line which is Dividing it into two triangles. The property used here is SAS or Side-angle-side Property.
to find the area you have to do:
Area = π( D/2)^2 and in this case D = 19 so..
π(19/2)^2
=90.25π
=283.52873698648
Answer: 283.53
