1.given a= -1 b= 2 c=-3 find the value of a +b+c

The cost c, in dollars, for bananas depends on the weight w,in pounds, of the bananas. this situation is represented by the function rule c=0.5w (graph each function rule.tell whether the graph is continuous or discrete)

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

Can someone check if i did this correct. it’s number 4 if you’re wondering.
