Answer:

Step-by-step explanation:
We know that
Length(l) = 1.5n + 9 ft
Width(w) = 5n - 1.5 ft
The formula for the perimeter(P) of a rectangle is:

So by substituting l and w we get :
![P= 2[(1.5n+9)+(5n-1.5)]](https://tex.z-dn.net/?f=P%3D%202%5B%281.5n%2B9%29%2B%285n-1.5%29%5D)
![P= 2[(1.5n+9)+(5n-1.5)]](https://tex.z-dn.net/?f=P%3D%202%5B%281.5n%2B9%29%2B%285n-1.5%29%5D)
![P= 2[1.5n+5n+9-1.5]](https://tex.z-dn.net/?f=P%3D%202%5B1.5n%2B5n%2B9-1.5%5D)
![P= 2[6.5n+7.5]](https://tex.z-dn.net/?f=P%3D%202%5B6.5n%2B7.5%5D)

Answer:
congruent
Step-by-step explanation:
If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. When two adjacent angles form a linear pair, their non-shared sides form a straight line (m).
i'm not sure tho
Answer: 11 shelves
Step-by-step explanation:
Total number of juice boxes:
= 32 + 56
= 88 boxes
Each cupholder holds 8 boxes. Number of shelves needed is:
= Number of boxes / Boxes per holder
= 88 boxes / 8 boxes per holder
= 11 shelves
Answer:
(7m + 63)/3x = k
Step-by-step explanation:
<em>m=3kx/7 - 9</em>
<u><em>add 9 to both sides:</em></u>
m+ 9 = 3kx/7
<u><em>multiply both sides by 7:</em></u>
7(m+9) = 3kx
<u><em>distribute the 7:</em></u>
7m+63 = 3kx
<u><em>divide both sides by 3x:</em></u>
<u>(7m + 63)/3x = k</u>
