Two boxes are stacked together. what is the combined volume of the two boxes? a. 105 cm b. 280 cm c. 385 cm d. 4,200 cm

The formula of a volume of a rectangle prism:

l - length

w - width

h - height

The larger rectangle prism:

Substitute:

The smaller rectangle prism:

Substitute:

Total volume:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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.
