Help me please in part “A” and part “B”

Alla [95]

The two expressions are equal because in the second expression all they did was move the decimal over one place to make it so both numbers had the same exponent value.
Part B:
The second expression takes less steps to solve because you can simply subtract the two numbers.

Danielle wants to know if a new dresser will fit next to her bed. The dresser she would like to buy is 73 centimeters wide. She

zhannawk [14.2K]

Answer:

No.

The dresser's width(28.74in) is greater than the remaining free width(10in) in the room.

Step-by-step explanation:

First, convert the chest width into inches, $73cm=28.74 \ in$

To find the excess width after fitting the bed in her room, we subtract the bed width from the room's width:

$Width_R=86 \ in\\Width_B=76 \ in\\\\Width_{excess}=Width_R-Width_B\\\\=86\ in -76\ in\\\\=10\ in$

Since 10in is less than 28.74in, the dresser will not fit next to her bed.
