Answer:
-11/14
Step-by-step explanation: first you divide 33/4 and (-21/2), then reduce the numbers to -33/4 times 2/21 after you reduce both fractions multiply -11/2 times 1/7 and you get -11/14 your alternative form would br -0.785714
We need to now the diameter or radius to find out the circumference.
R times 2 then multiply the product with 3.14
or
D times 3.14
I’m not sure the answer but go into a webpage called Desmos and it will show you
Answer:
2(x+6)(x-3)
Step-by-step explanation:
Factor the GCF out of the trinomial on the left side of the equation.

Greatest common factor of 2, 6, 18 is 2
so GCF is 2
divide each term when we take out GCF 2
so 
now factor the trinomial
product is -18 and sum is +3
6 times -3 is -18 and 6-3=3
