(3+a+2) (a+2-3)
(5+a) (a-1)
5a-5+a^2-a
Rearrange and combine like terms
a^2 +4a-5
Karen bought 8.5 pounds of flour. She uses only 2.5 pounds of flour to make the bread.
So, the amount of flour left after baking the bread = (8.5 - 2.5) pounds
= 6 pounds
So 6 pounds of flour is left. She breaks this 6 pounds of flour into several bags and each bag contains 2/5 pound of flour.
Now to calculate the 2/5 th pound of flour in decimal, we get = 0.4 pounds
So each of the bags contain 0.4 pounds of flour. Now we have to calculate the number of bags in which the flour have been kept.
So,
Number of bags required = 6/0.4
= 15
So 15 small storage bags are required by Karen to keep the remaining flour.
Answer:
(-2,-1)
Step-by-step explanation:
If you look at the graph, you can see that the lines will extend upwards indefinitely, but the lines will stop going downwards at y = -1
When y = -1, x = -2
Therefore, the values of x for the given values of y when y<0 is (-2,-1)
