Question
Rectangles A and B are similar. An expression that represents the width of each rectangle is shown. Find the scale factor of rectangle A to rectangle B in the simplest form.


- (x – 5)
- (x + 5)(x - 4)
- (x – 5)(x + 4)
- x(x + 4)
Hint:
In the given question rectangles are similar also we have to find the scale factor of the width,
.
The correct answer is: (x – 5)(x + 4)

Aisha paddles a kayak 5 miles downstream at a rate 3 mph faster than the river’s current. She then travels 4 miles back upstream at a rate 1 mph slower than the river’s current. Hint: Let x represent the rate of the river current.

Write and simplify an expression to represent the total time it takes Aisha to paddle the kayak 5 miles downstream and 4 miles upstream.
speed downstream= speed of boat + speed of current and speed upstream = speed of boat - speed of current
