Step-by-step explanation:
the intersection of the interval: (-∞, 7) and [-5, +∞)
is [-5,  7)
and the union of the interval: (-∞, 7) and [-5, +∞)
is (-oo,  +oo) 
 
        
             
        
        
        
Total cost for tiles and paints is $924. 
Step-by-step explanation:
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
Therefore, the area of walls and ceiling is 1410 square meters.
Given: Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. Therefore, 
Therefore, the total painting cost is $564. 
Tiles will be required for floor. Let us find the area of floor.
Given: 1m squared floor tiles costs $3. So,
Therefore, the total cost for tiles is $360. 
Now let us find combined total cost of tiles and paint.
Therefore, the combined total cost of tiles and paint is $924.

Answer: <em>33 square feet</em>
Step-by-step explanation:
<em>First, let's take the area of the rectangle shown here which is 6ft long and 4ft wide</em>
<em>6x4=24</em>
<em>Now let's take the area of the square which is 3ft long and 3ft wide</em>
<em>3x3=9</em>
<em>Now add 24 and 9 for the total area</em>
<em>24+9=</em><em>33 square feet</em>
