The difference will be

.
Remember that parentheses are needed for the second polynomial because the negative is distributed to all of its terms.
P = 5
I am not sure if this is correct. However, P is used to represent the addresses and there are 5 addresses. Therefore p = 5.
To find the total length of the two copper pipes, we need to add them together.
2 5/12 + 3 7/12 = 5 12/12
Since 12/12 = 1 or a whole, we can simplify this further.
5 12/12 = 6
Hope this helps!
The second one. Hope this helps:)
6,025, 305< 6,026,305< 6,027,305.
<span>We cannot deduce about the exact location of P between J and K. But we can conclude: segment JP + segment PK = line JK.
</span><span>JP + PK = JK.
</span><span>Substitute first each.
(8z - 17) + (5z + 37) = 17z - 4
Combine like terms.
13z + 20 = 17z - 4
Isolate the variable z.
4z = 24
z = 6
The value of the variable z is then 6 units.</span>
