Using Heron's formula:
A = √(p(p-a)(p-b)(p-c)) where a,b,c are the sides of the triangle and p is half the perimeter.
The answer is B. 149.4 square units.
It wants you to complete the function using -10 for x. . .
e.g: f(x) = 1/2x + 2
f(-10) = 1/2(-10) + 2
f(-10) = 3
5y - 5= 22
or
5(y)-5=22
Hope that helps!
