How could you find the perimeter of an isosceles right triangle if you (8) already know the area?

The area of a triangle is given in terms of the side lengths (b, h) as

... A = (1/2)bh

If b=h, then we can find the side length as ...

... A = (1/2)b²

... b = √(2A) . . . . . multiply by 2 and take the square root

The hypotenuse (x) can be found from the Pythagorean theorem:

... x² = b² + h² = 2b²

... x = b√2

The perimeter is the sum of the side lengths, so is

... P = b + b + x = 2√(2A) + (√(2A))·√2

... P = (2+√2)·√(2A)

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
