Answer:
C.Infinitely many solutions
I solved by substitution
Infinitely many solutions
(x+1)2-
=it is meant to be (x+1)2
=2(x) + 2(1)
= 2x +2
I think
All the answers are correct.
I am not sure if I am correct.
I think that the angles did not help to solve the problem, ( it makes an obtuse angle)
and the unit rate is 421 mph and 384 mph.
2*421+384*2= 1610 miles
or
2 (421+384)= 1610 miles
Answer: 1610 miles
I think the answer is going to be 3s
