Answer:
18.6x + 3.6
Explanation:
A rocket scientist needs to find the overall thrust of a new rocket design. The rocket has two stages: Stage A and Stage B. Stage A's thrust is defined by the expression 11.2x + 6.4 and Stage B's thrust is defined by the expression 7.4x − 2.9.
Solution:
The rocket thrust is the force that helps in moving the rocket through air and through space. For a multistage rocket, the overall thrust is gotten by summing all the thrust experienced in each of the stages.
Hence the overall thrust for this problem is given by the equation:
Overall thrust = Stage A thrust + stage B thrust
Overall thrust = (11.2x + 6.4) + (7.4x − 2.9)
Overall thrust = 18.6x + 3.6

Explanation:
The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric.
The characteristic that best represents good walking technique is letting your arms swing loosely and your feet so they move fluidly and finding great balance so you last longer. So the best answer to your question is letter D. I hope this helps.
