Sydney is cutting the crust from the edges of her sandwich. The dimensions, in centimeters, of the sandwich is shown.

The response is 8x^2 + 34; 45.52 centimeters. Step-by-step explanation: The perimeter is calculated as twice the sum of the adjacent sides of the rectangle: P = 2((2x^2 +9) +(2x^2 +8)) = 2(4x^2 +17) = P = 8x^2 +34. When x=1.2, the perimeter becomes P = 8(1.2^2) +34 = 8·1.44 +34 = 45.52 cm.

The answer is B: 8x^2 + 34; 45.52 centimeters. Step-by-step explanation: This was addressed based on the edge.
