455 cubic centimeters =
455 milliliters
Let x represent the length of the shorter leg.
Longer leg: 5x +19
Hypotenuse: 5x +20
Pythagorean theorem:
.. x^2 +(5x +19)^2 = (5x +20)^2
.. x^2 +25x^2 +190x +19^2 = 25x^2 +200x +20^2 . . . . . . eliminate parentheses
.. x^2 -10x -39 = 0
.. (x -13)(x +3) = 0
.. x = 13 . . . . . . . . . . leg lengths must be positive
The side length of the triangle are 13, 84, 85 feet.
The rate of change is +(-1) or -1
12/6 = 2 10/0.0001 = 1000002*100000 = 200000When doing these problems try and see the numbers not as the whole number but in standard form, if you want to understand further ask a maths professor about standard form
