Evaluate the following polynomial expression when a = 2, b = 5, and c = -5. ab-3bc + 3 abc

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
