(1 point) You wish to pack a cardboard box inside a wooden crate. In order to have room for the packing materials, you need to leave a 0.5 \ \mbox{ft} space around the front, back, and sides of the box, and a 1 \ \mbox{ft} space around the top and bottom of the box. If the cardboard box is x feet long, (x 3) feet wide, and (x-1) feet deep, find a formula in terms of x for the amount of packing material, M, needed. M(x)

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

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

b). 4320 have a nice day
