The values of the expression are;

-21, 240, 310 respectively

We were given the equation as ;

20 [tex]m^{2}[/tex] + 30m + 40

Then we can find the values of the expression with the given options to know the answer by input the value of ' m' into the given equation

  • Option (a) (m=-3)

  • 20( [tex]-3^{2}[/tex] )+ 30(-3)+ 40 = -21

  • Option (b) (m=-4)
  • 20([tex]-4^{2}[/tex] )+ 30(-4)+ 40 = 240

  • Option (c) (m=3)
  • 20([tex]3^{2}[/tex]) + 30(3)+ 40 = 310

Therefore, the values of the expression are; -21, 240, 310 respectively
