The volume of a gas varies directly with
temperature, T, and inversely with pressure, P.
Which of the following equations represents that
relationship?

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

pi x^2

step-by-step explanation:

pi times x squared

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

the terms in pattern b are 4 times the terms in pattern a
