Answer:
x = -5/2 + root(33)/2 or x = -5/2 - root(33)/2
Step-by-step explanation:
ok so your computer is
saying:
x^2 + 5x = 2
and takes the 5 divides it by 2 and squares the result
x^2 + 5x + 25/4 = 2 + 25 /4 but then replaces a trinomial with a binomial
(x + 5/2)^2 = 2 + 25/4 = 33/4
solving
x = -5/2 + root(33/4) or x = -5/2 - root(33/4)
or
x = -5/2 + root(33)/2 or x = -5/2 - root(33)/2
Area of the first one is has a area of 162
the second one has a area of 189
the third one has an area of 162
the fourth one has a area of 12
Answer:
2
to find the slope you get the rise which is the difference between the y coordinates over the run which is the difference between the x coordinates. so 6/3=2
