Answer:
18 pots.
Step-by-step explanation:
10/2 to get one of the longs. 5(2) to get the other one. 10.
8/4 to get one of the wides. 2(2) to get the other one. 4.
There are 4 corners so there are 4 extra pots. 4.
Add the numbers: 4+4+10. 18
Answer:
11/5
Step-by-step explanation:
We can find the slope by
m = (y2-y1)/(x2-x1)
= (5 - -6)/(-4 - -9)
= (5+6)/(-4+9)
= 11/5
Answer:

Step-by-step explanation:
The cost (in dollars) in making b bracelets is represented is

The cost (in dollars) of making b necklaces is

To find how much more it will cost to make b necklaces than b bracelets, we find the difference,




This is a polynomial in descending powers of b, hence it is in standard form;
Y^2-9^2
(y-9)(y+9)
To see if its right:
y*y+y*9-9*y-9*9
y^2+9y-9y-81
y^2-9^2
