Sample Response:  for edge.. users

Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

Demetrius Scored 28 points in5 56 minutes duringa game of tennis. How many points did he average per minute during that
slava [35]

Answer:

420/89

Step-by-step explanation:

What we know:

Demetrius scored 28 points in 356 seconds.

To get the per second rate divide 28 by 356.

28/356 = 7/89

Here, we're looking for the per minute rate, so multiply the previous rate by 60.

(7*60)/89 = 420/89 (Since this asks for an improper fraction, I'll keep it as so.)

What is the slope of a line that is parallel to the line joining (7,-5) and (-5,7)
brilliants [131]

Answer:

Step-by-step explanation:

If two lines are parallel then they will have the same slope. So all you need to do is find the slope of the line that joins the two given points. You can use the slope formula \frac{y_2-y_1}{x_2-x_1}. You can also graph the two points and use rise over run. \frac{7-(-5)}{-5-7} =\frac{12}{-12}=-1
