Two polynomials are added and the sum is 3x^2-y+4. For each statement, state weather it is always true, sometimes true or never true. Explain or provide a counter example to justify our answer.
a) both are monomials

b) both include a y-term

c) if there is a x-term in one polynomial, then there must be a x-term in the other

d) both are monomials

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

saving = more money

step-by-step explanation:

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.
