$-(x+2)-2x=-2(x+1)\\\\-x-2-2x=-2x-2\\\\-3x-2=-2x-2\ \ \ \ \ \ |add\ 2\ to\ both\ sides\\\\-3x=-2x\ \ \ \ \ \ \ \ |add\ 2x\ to\ both\ sides\\\\-x=0\\\\\boxed{x=0}$

Can someone help me?

Answer:

Volume of a Rectangluar Prism: 288 ft

Volume of triangular prism: 12 ft

Volume of composite figure: 300 ft cubed (^3)

Step-by-step explanation:

Volume of a Rectangluar Prism: V=lwh

$4 \times 6 \times 12 = 288$

Volume of triangular prism: For this instance, we'll use V=1/2bh

$\frac{4 \times 6}{2} = 12$

The volume of the composite figure is the total of the volumes added

$288 + 12 = 300ft ^{3}$
