Answer:
Breadth = 15 cm
Step-by-step explanation:
Area = length x breadth
315 = 21 x breadth
[ dividing both sides by 21 ]

Answer: 4
Step-by-step explanation:
18-14=4
Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
The answer would be they are congruent.
It's because there was no vertical/horizontal stretch and compression listed in the problem's transformations. The figure was translated throughout the graph.
