Next would be to subtract 4 from both sides:
2x + 4 (- 4) = 16 (- 4)
2x = 12
The total distance is D=d1+d2+d3
d1=30x0.5
d2=50x1
d3=30x0.5
D=d1+d2+d3=80miles
Area = Length * Width
A = (2x - 4) * (x + 5)
A = 2x² +10x-4x - 20
A = 2x² + 6x - 20
In short, Your Answer would be Option C
Hope this helps!
2x is not a way to express this. You could use 2 + x or x +2. But 2x is x multiplied by 2. x + 2 is x plus 2.
