So, the question said that n=5 so we will input 5 to replace n.
5(5+2)-15
Now, solve the problem
5(5+2)-15
5 x 7- 15
35-15
20
Thus, the answer is 20

Answer: 11.1 m
Step-by-step explanation:
This can be solved by the Pythagorean theorem where;
c² = a² + b²
c is the hypotenuse which is the distance from the top of the building to the tip of the shadow.
a is the height
c is the length
32² = 30² + b²
b² = 32² - 30²
b² = 1,024 - 900
b² = 124
b = √124
b = 11.1 m
C because 3 is the intercept and -2 is the slope
