The expression that represents the tape diagram are B, C and E.
Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).
From the tape diagram:
The expression is,
87 - (39 + 4x).
(A).
There are 87 children and 39 adults at a show. The seating in the theater is split into 4 equal sections.
The expression: (87 + 39)/4x.
(B). There are 87 first-graders in after-care. After 39 student are picked up, the teacher put the remaining students into 4 groups for an activity.
The expression: 87 - (39 + 4x).
(C). Lin buys a pack of 87 pencils. She gives 39 to her teacher and shared the remaining pencils between herself and 3 friends.
The expression: 87 - (39 + 4x).
(D). Andre buys 4 packs of paper clips with 39 paper clips in each. Then he gives 87 paper clips to his teacher.
The expression: 4(39) - 87
(E). Diego's family spends $87 on 4 tickets to the fair and a $39 dinner.
The expression: 87 - (39 + 4x).
Therefore, the equivalent expressions are B, C and E.

Answer:
eight cubes can be shipped.
Step-by-step explanation:
The height of the shipping box is the same as the height of the boxes that are about to be shipped. (4 1/2 inches). So you can get 1 layer of the boxes to be shipped.
The length of the shipping box is 18 inches. You will be able to get 18/4.5 = 4 boxes along the 18 inch side.
The 9 inch side will allow 2 boxes.
In all you can ship 2 * 4 boxes in the shipping box which is eight 4 1/2 inch cubes in all.
