Which expression represents the total perimeter of her sandwich, and if x = 1.2, what is the approximate length of the crust?

8x2 + 34; 43.6 centimeters

8x2 + 34; 45.52 centimeters

4x2 + 17; 21.8 centimeters

4x2 + 17; 22.76 centimeters

Substituting the value of X in each of the equations. The best answer would be the equation satisfying both of the sides.

Therefore,

Substituting the values in the second equation gives the best answer.

8 (1.2) ^2 + 34 = 45.52 centimeters
