Answer:
2) 11
3) 21
4) 7
Step-by-step explanation:
2) (-6) -(-17) = 17 - 6 = 11
3) 19 - (-2) = 19 + 2 = 21
4) (-13) + 20 = 20 - 13 = 7
Answer:
OA
Step-by-step explanation:
yax2;
12+34+5+6=21 so y2+35
For this case we have the following data:


So that the figure can be a rectangle, its diagonals must be equal, that is, 
In this way we have:

Clearing x we have:


Thus, x must be equal to 10 so that the figure is a rectangle.
Answer:

Option A
Given:
A right rectangular prism is packed with cubes of side length
inch.
Prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height.
To find:
The volume of the prism
Solution:
Side length of each cube
inch.
15 cubes along the length, so length of prism is

6 cubes along the width, so width of prism is

5 cubes along the height, so height of prism is

Now,
Volume of rectangular prism is





Therefore, the correct option is B.
