The width of bookcase D is 61 cm
The width of bookcase E is 61 cm
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Sum the widths of the three bookcases A, B and C
step 2
Subtract the sum of the three bookcases A,B and C from the total length of the wall
step 3
Divide that answer in step 2 by 2, and that will let you know the widths of D and E, because they may have equal widths
therefore
The width of bookcase D is 61 cm
The width of bookcase E is 61 cm

The atomic number is equal to the number of <u>protons</u> in an atom
The atomic number tells you the number of protons in one atom of an element. It also tells you the number of electrons in a neutral atom of that element. The atomic number gives the “identity “of an element as well as its location on the Periodic Table.
