Let
x--------> number of dogs that completed the obedience class
we know that
total number of dogs=5
<span>Eighty percent of the dogs have completed obedience classes
so
x=0.80*5------> x=4
the answer is
4 dogs </span>have completed obedience classes
Answer:
-2
Step-by-step explanation:
x^2 + x=2
Subtract 2 from each side
x^2 + x-2=2-2
x^2 + x-2=0
Factor
What 2 numbers multiply to -2 and add to 1
2*-1 = -2
2+-1 =1
(x-1)(x+2)=0
Using the zero product property
x-1 = 0 x+2 = 0
x=1 x = -2
Product of the roots
1*-2 = -2
