Pretty sure it’s d. 5,000 kilograms
On 3 and 6 you did not clarify whether it is addition, subtraction, multiplication, or division.
Therefore, I have worked out all possible solutions.
If 2(3 - 6 x 3 - 5) then the solution is 12.<span>
If 2(3 + 6 x 3 - 5) then the solution is -36.</span><span>
If 2(3 / 6 x 3 - 5) then the solution is -2.
If 2(3 x 6 x 3 - 5) then the solution is -72.</span>
F(x) = (2x-1)(x+2)/ (x+2)
f(x) = 2x-1
f(-2) = 2(-2)-1
f(-2) = -5
