5n + 13.....n = -5
5(-5) + 13 =
-25 + 13 =
-12
4n + 8.....n = -5 <===
4(-5) + 8 =
-20 + 8 =
-12
125feet/5sec = 25feet/sec
I’m sure your answer is D. 180 - 125 will get you 55.!

Answer:
9?
Step-by-step explanation:
im just guessing tho sorry if im wrong
Answer:
Distance between bottom of the wall and bottom of the ladder = 7 ft
Length of the ladder = 19 ft
Let the distance between the ground and top of the ladder be x
Using Pythagoras theorem,
x^2 + 7^2 = 19^2
x^2 + 49 = 361
x^2 = 312
Therefore x = √312 = 2√78 ft
