Which graph shows the solution to the inequality -3-7< 20

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

The table below shows the function f. determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5]. a. 32 b. -32 c. 25 d. -25

Can someone me with this? i’m not sure what to put for my equations.
