V/w=9. Find the constant of variation if, a) v varies directly with w.
b) w varies directly with v.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405

16 is the coefficient

hope this
