Answer:

Step-by-step explanation:
First FOIL (n + 7)(n + 8) and then distribute n
(n + 7)(n + 8) = 
n (
)
= 
3x-8 = 8x+4
subtract 3x from each side
-8 = 5x+4
subtract 4 from each side
-12 = 5x
divide -12 by 5 to get x
x = -12/5 = -2.4
Answer:
40%
Step-by-step explanation:
She has sold 20 items total.
Refrigerators: 8/20 = 40%
Dishwashers: 1/20 = 5%
Dryers: 11/20 = 55%
So there is a 40% chance she will sell another refrigerator! hope this helps!!
Use the coordinates of the two black dots:
(2,3) and (7,6)
Slope is the change in Y over the change in X:
Slope = (6-3) / (7-2)
Slope = 3/5
The answer would be B, ||
