The number of closer does should be considered as the 139 miles.
Since Lori lives 272 miles from her grandparents, 411 miles from her favorite aunt, and 39 miles from her cousins.
So here the difference be like
= 411 - 272
= 139 miles
Hence, The number of closer does should be considered as the 139 miles.

Answer:
2/5
Step-by-step explanation:
Jill wants to eat the same amount of pie every day so we need to divide the amount of pie by the amount of time. This gives us 4/10 which simplifies to 2/5. She should bring 2/5 a pie each day.
Prove that the quadrilateral whose vertices are I(-2,3), J(2,6), K(7,6), and L(3, 3) is a rhombus.
I think in these problems the first step is to express each side as a vector. A vector is the difference between points. When two sides have the same vector (or negatives) it means they're parallel and congruent. So in a rhombus IJKL the vectors IJ and LK should be the same, as should JK and IL. That much assures a parallelogram; we check IJ and JK are congruent to complete the crowing of the rhombus.
Let's calculate these vectors:
IJ = J - I = (2,6) - (-2,3) = (2 - -2, 6 - 3) = (4, 3)
LK = K - L = (7, 6) - (3, 3) = (4, 3)
IJ = LK, so far so good
(Note: If you haven't got to vectors yet you can just show the two sides are the same length, 5, and have the same slope, 3/4, both of which can be read off the vectors.)
JK = K - J = (7,6) - (2,6) = (5,0)
IL = L - I = (3, 3) - (-2, 3) = (5, 0)
Those are the same too.
Now we have to show IJ ≅ JK
The length of IJ is the cliche √4²+3² = 5, the same as JK, so IJ ≅ JK
We showed all four sides are congruent and we have two pair of parallel sides, so we have a rhombus.
