So g(x) just means the function of the x term as the original value of this is 2x+1 then this is your starting point, when it says -2g(x) all you have to do is do the same to the other side of the equation so just do (2x+1) x -2 this would be -4x-2 as the signs would change due to the negative 2 as a positive and a negative make a negative so the answer is the second one -2g(x) = -4x-2
Hope this helps x

Answer:
From the diagram you can see that we have constructed a right triangle, with height A and base 15.Length of shadow = 15 feet.Height of flagpole = A.We know the angle of elevation is 40∘. Using this angle and the tangent ratio, we can find A.tan(40∘)=oppositeadjacent=A15∴tan(40∘)=A15Rearranging:A=15tan(40∘)By calculator:A=12.59 feet. ( 2 d.p.)
