Okay so 6.25 a student then it goes to 4.50 for 15 more students at 70 students its 358.75 now it drops another 1.75 so it would be 368.75 for 80 students so the equation is 4.48 x 80 = 368.75. enjoy :D
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.

Answer:
w = 2/3 AND w = 3
Step-by-step explanation:
Set 3w2-11w = -6
So 3w2-11w+6 = 0
Now factor: (3w-2)(w-3) = 0
So 3w-2 = 0 AND w-3 = 0
So w=2/3 AND w = 3
Answer:
6
Step-by-step explanation:
