Answer:
2/1 or 2overrun
Step-by-step explanation:
You can see that the rais/run for C to D is 2/1. So that would be the slope.
By the Pythagorean theorem
50^2 = x^2 +(x +34)^2
2500 = 2x^2 +68x + 1156
x^2 +34x -672 = 0
(x -14)(x +48) = 0
x = 14 or -48
The distance from the wall to the base of the ladder is 14 ft.

7-24-25 is a Pythagorean triple. The dimensions here are double those values. It can be handy to know a few of the Pythagorean triples, as that can let you write down the answers to problems without having to go through the equations.
Answer:
The answer is A.
Step-by-step explanation:
So we have the two equations:

To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:

Now, we can substitute this into the first equation. Therefore:
