Hey there!
I just worked it out and the answer is D. 4y^2-10y-1
I’ve just studied these long equations and then having to simplify the expressions in algebra. I really hope my answer benefits you in the best way!

2÷5=2.5
4÷10=2.5
that is about it
with it's formula
Area of Triangle = (1/2)(ab)sin(C) – This formula is used when two sides and the angle in between them are known. It can be obtained from the basic formula, Area of Triangle = 0.5 × base × height. The height with respect to side 'a' can be written in as b×sin(C), where C is the angle between a and b.
