92 cubic ft

Step-by-step explanation:

Left cube:

length = (12 - 7) = 5 ft

width  = 2 ft

Height = (5 - 3) = 2ft

Volume of left cube = length * width * height

             = 5 * 2 * 2

             = 20 cubic ft

Right cube:

length =12 ft

width  = 3 ft

Height =  2ft

Volume of right cube = length * width * height

             = 12 * 3 * 2

             =  72 cubic ft

Volume of figure = 72 + 20 = 92 cubic ft

true

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
