Solve by first completing the square
x^2+6x+3=0
can anyone me

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

If f(x) = -5x + 1 and g(x) = x3, what is (gºf)(0)? enter the correct answer

Extremely mega ultra important question! plss answer as fast as you can you will get 84 points! the area of this right triangle is half the area of which of these rectangles?
