I think it is negative five
4x+2(3-2x)=10, 4x+6-4x=10, x+6=10, x=4
Answer: D
1/2x-1+4=x
1/2x-x=-3
-1/2x=-3
x=6
Answer:
D. 
Step-by-step explanation:
Area of sector of a circle is given as θ/360*πr²
Where,
r = radius = 12 cm
θ = 56°
Use 3.14 as π
Plug in the values into the formula and solve


Area of the sector ABC =
The answer is D
