The formula of a volume of a rectangular prism: V = lwh

l - length

w - width

h - height

We have the volume:

$V=6x^3-x^2-2x=x(6x^2-x-2)=x(6x^2+3x-4x-2)\\\\=x[3x(2x+1)-2(2x+1)]=x(2x+1)(3x-2)\\\\Answer:\ \boxed{A.\ Height:3x-2,\ Length:2x+1,\ Width:x}$

Kelly pays $25/sweater wholesale.find the salling price if her mark-up is 65%?

gladu [14]

This is another way of saying what is 165% of 25, because 65% of the sweater is the markup, and you add the markup to the whole sale.
165% is 1.65 in decimal form, so $1.65*25=41.25$
$41.25$ is your answer
