The circumference of a circle measures 22π units. Find the number of square units in the area of the circle. Express your answer in terms of π.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

explanation:

remove parenthesis:

=

apply rule

=

multiply fractions:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

this is a good question! i'll do some research and come back when i have the answer!
