Volume (V) is (=) Length (L) times (x) Width (W) times (x) Height (H) so V = L x V x H. 
Add the variables to the equation.
V = 24 x 10 x 13
Solve
V = 3120
So the volume of the gift box is 3120 cm
        
             
        
        
        
Answer:
<h3>It's answer is D. 11 </h3>
Here we can see there is modulus so 
while doing calculation 
| -3-8 |
| -11 |
Here it is modulus so - changes into +
so it's answer is 11.
 
        
             
        
        
        
Answer:
2/10
Step-by-step explanation:
you have to match the bottom number on both fractions then do what ever you did to the top number
so with this to get the 5 to a 10 you have to times it by 2
so you do the same to the 1
 
        
             
        
        
        
Answer:
Elissa needs 4 quarts of paint, or 1 gallon. 
Step-by-step explanation:
Elissa's room is in the shape of a rectangular prism.  Assuming that she will only be painting the walls and not the floor or ceiling, you just need to calculate the area of the four walls - front and back and side to side.  Based on the dimensions given, the area of Elissa's front and back walls are 8 ft x 9 ft or 72 ft² for each wall.  Since there are two, we take that area times two: 72 x 2 = 144 ft².
Elissa's side walls are 8 ft x 13 ft or 104 ft² for each wall.  Since there are two, we take this area times two:  104 x 2 = 208 ft².
To find the total area needed to paint, we add all four walls:  144 + 208 = 352 ft².  Since a quart of paint covers 100 ft² and a gallon covers 400 ft², Elissa can either purchase 4 quarts of paint or 1 gallon to paint her bedroom. 
 
        
             
        
        
        
4x+2x^2+3x-2x+7
First, you would combine like terms. In this case, you would add 4x and 3x then subtract 2x. 
2x^2+5x+7
5x^2-2x+3+4x-2x^2
Once again, you must combine like terms. Subtract 2x^2 from 5x^2, then subtract 2x from 4x.
3x^2+2x+3
There you go! Hope it helps
