Arestaurant earns $1073 on friday and $1108 on saturday. write and solve an equation to find the amount xx (in dollars) the restaurant needs to earn on sunday to average $1000 per day over the three-day period. write your equation so that the units on each side of the equation are dollars per day.
using sum and product method you can simplify the top as:
x^2-4x-5 = (x-5)(x+1) and x^2-5x+4 = (x-4)(x-1)
the x-4 and the x+1 cancel each other out and you will be left with
180, 90, side and vertex, same, obtuse, isosceles right triangle.
