Find the volume of each rectangular prism

385

Step-by-step explanation:

L=Length

W=Width

H=Height

L=7

W=2

H=4

7 x 2 x 4

7 x 2 = 14

14 x 4 = 56

Rearranging to check my work:

7 x 4 x 2

7 x 4 = 28

28 x 2 = 56

I was right.

Hope this answers your question.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
