Answer:
D) 45 ft
Step-by-step explanation:
The two triangles are shown below.
Given:
BC = 60 ft, CD = 24 ft and DE = 18 ft.
Since, the two triangles are similar, their corresponding sides are in proportion.
So, 
Now, consider the proportion of sides,

Therefore, the distance between A and B is 45 ft.
5/32 divided by 25/4 is 1/40
Answer:
Step-by-step explanation:
System A
the two lines have the same slope, so they are parallel and never intercept themselves.
the system has no solution.
System B
By multiplying the first equation by -1
x + 4y = -3
The two equations are equals so the lines are the same.
The system has infinitely many solutions
