Answer:
An expression for the number of miles Jessica rode is, 9 + r
Step-by-step explanation:
Here, r represents the number of miles Roger rode.
Given the statement: Jessica rode 9 miles farther than Roger rode.
"Farther" means greater distance from something.
"9 miles farther than Roger rode" means 9 + r
then;
the equation of the statement become:
Therefore, an expression for the number of miles Jessica rode is, 9 + r

Answer:
Base of the ladder is 3 meters away from the building.
Step-by-step explanation:
Let's use Pythagoras theorem to solve.
Pythagoras theorem says,
Here let horizontal distance is "a''
Vertical distance of window is 4 m
So, b=4
The Rafi leans 5 m ladder against the wall. So, c=5.
Simplify it
Subtract both sides 16
Take square root on both sides
a=±3
So, base of the ladder is 3 meters away from the building.
Rationalize both the numerator and denominator. Given
we can rationalize it by introducing conjugates of the numerator and denominator:
Then the limit is equivalent to
For the remaining expression, divide through uniformly by :
As <em>n</em> goes to infinity, the remaining terms containing <em>n</em> converge to 0, leaving
making the overall limit 3.
