4 x  (3+6) = 12 + 24 ---->Distributive
3 + ( 8 + 2) = 3 + (2 + 8) ---> Commutative
6 x (7 x 3 ) = (6 x 7 ) x 3 --->Associative
 
        
                    
             
        
        
        
Answer:
- Tamara needs to cover a total of <u>476</u> square feet.
 - Tamara <u>will</u> have enough material to cover all four walls.
 
Step-by-step explanation:
If the room dimensions are 8 1/3 feet by 11 1/2 feet, the perimeter length is ...
   P = 2(L+W) = 2(8 1/3 +11 1/2) = 2(19 5/6) = 39 2/3 feet
The area of the walls is the product of this perimeter length and the height of the wall. If that height is 12 feet, then the wall area is ...
   A = PH = (39 2/3 ft)(12 ft) = 476 ft²
Tamara needs to cover a total of <u>476</u> square feet.
__
If Tamara orders 480 square feet of material, ...
Tamara <u>will</u> have enough to cover all four walls.
 
        
             
        
        
        
Answer:
-9
Step-by-step explanation:
The sum of -2 and -7 is given as follows;
-2 + (-7)
In mathematical operations, +  *  - is -. 
So we have;
-2 - 7
This gives us: -9
 
        
             
        
        
        
Answer:

Period is 2π 
Horizontal shift = 0
Step-by-step explanation:
We know that 
 and as 
, so, we can write 
Therefore, the if 
 then 
 (Answer)
Now, the period of 
 is 2π, hence the period of 
 is also 2π.  (Answer)
Again. 
, hence, the horizontal shift of 
 is 0. (Answer)
 
        
             
        
        
        
Quadratic Equation in Standard Form: ax2 + bx + c = 0.
Quadratic Equations can be factored.
Quadratic Formula: x = −b ± √(b2 − 4ac) 2a.
When the Discriminant (b2−4ac) is: positive, there are 2 real solutions. zero, there is one real solution. negative, there are 2 complex solutions.
