Answer:
56
Step-by-step explanation:
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.
She earned 1149, which is between 436 and 1506 so you would use the 2nd row for the information.
the tax rate says 15% for the amount over 436
so fist find the amount that is taxable:
1149 - 436 = 713
now multiply that amount by 0.15 ( 15% as a decimal)
713 * 0.15 = 106.95
now add the base tax to that amount for the total amount of tax:
106.95 + 34.90 = 141.85 total tax withheld
To find slope use the formula M = y2 - y1
-----------
x2 - y1
say you were given this (2,3) (-4,5) 2 would be x1 and 3 would be y1, -4 would be x2 and 5 would be y2 then just put it into the formula 5 - 3
--------
-4 - 2
which would be 2/ -6 which would simplify to 1/3
