Answer:

I would choose two 12 inch pizza if I want more pizza as two 12 inch pizzas have larger circumference than one 18 inch pizza

c=πd

circumference= pie × diameter

c=2πr

circumference= 2×pie×radius

A=πr²

Area= pie×square radius

Pie= 22/7, 3.14( depends on the question, sometimes the value of pie will be given in the question)

radius= half of diameter

To find perimeter of circle use 2πr

To find area of circle use πr² or πd

(-3x)²-(3x-2)²-6*(2x-1.5)

Ilya [14]

Without the instructions, I can only assume that you are to "expand the given expression."

Following order of operations rules requires that (3x-2)^2 and -6(2x-1.5) be evaluated first.

(3x-2)^2 = 9x^2 - 12x + 4 and -6(2x-1.5) = -12x + 9

Then we have 9x^2 - (9x^2 - 12x + 4) -12x + 9

the 9x^2 terms cancel, leaving us with 12x - 4 - 12x + 9 = 5 (answer)
