Provide an appropriate response.To make a rope ladder, Alyssa needs two lengths of nylon rope for the sides of the ladder and six shorter lengths of rope for the rungs. The side pieces have length (2x + 1) meters and the rung pieces have length (x - 1.4) meters. Write a simplified algebraic expression that represents the total length of nylon rope that Alyssa would need to make a rope ladder and use it to find the total length if x = 2.4.
A. (10x - 0.4) meters; 23.6 meters
B. (3x - 0.4) meters; 6.8 meters
C. (10x + 2.4) meters; 26.4 meters
D. (10x - 6.4) meters; 17.6 meters
