I believe it is option 2, sorry if incorrect
So in a 8 hour workday he would make $72... 9x8=72
now 155-72= 83
83/6= a little over 13
so he would at least have to make 14 deliveries

ik its late but the correct answer is C:(2,-2)
Step-by-step explanation:
I got the answer correct on Edge 2020.
Hope this helps!!
Assuming it forms a right triangle with the side of the building, you could just use the Pythagorean Theorem to find the height. The ladder would be the hypotenuse, so you would substitute that as c into the equation. The 4 feet could be either a or b; it doesn't really matter. Plug it into (a^2)+(b^2)=(c^2), and you would get. (4^2)+(b^2)=(14^2); simplified, it is (16)+(b^2)=(196). Subtract 16 from 196 to get 180, and you see that (b^2) is equal to 180. Just take the square root of that to get your answer, which would be 6 sqrt5.
