Let f(x)=7x^3 −2x−12 and g(x)=−3x^3 -8x^2 +10x . what is the function rule for (f+g)(x) ? a.(f+g)(x)=4x^6 −8x^2 +8x−12 b.(f+g)(x)=4x^3 −12x^2 +8x−12 c.(f+g)(x)=4x^3−8x^2+8x−12 d.(f+g)(x)=4x^6−8x^2+12x−12

Ineed with this. the figure is made up of a square and a rectangle. find the area of the shaded region.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98

1mile equals approximately 1.6 kilometers. which best approximates the number of miles in 6 kilometers?
