monitta

Answer: B. 2=3x+10x^2

Step-by-step explanation:

The expression means the quadratic function equation.

B = 10x^2 + 3x -2 = 0

the equation is [-b ±√(b^2 -4ac)]/2a

b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.

Answer:

Total Area = Area of Triangle + Area of Semicircle

Total Area = 1/2(bh) + 1/2(pir^2)

Total Area = 60 + 18(3.14)

Total Area = 116.52
