Answer:
Step-by-step explanation:
Multiply the three dimensions 
12 x 6 x 8 = 576 cm^3
 
        
                    
             
        
        
        
Answer:
A and C
Step-by-step explanation:
solving the equations
A
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ±  = ± 2 ← required solution
 = ± 2 ← required solution
B
x² = - 4 ← has no real solutions
C
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ±  = ± 2 ← required solution
 = ± 2 ← required solution
D
2(x - 2)² = 0 , then
x- 2 = 0 ( add 2 to both sides )
x = 2 ← not the required solution
 
 
        
                    
             
        
        
        
Answer:
4 or 4.75
 or 4.75
Step-by-step explanation:
first we're going to convert the number into improper fractions.
7 =
=  and 2
 and 2 =
= 
For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply  x2, it'll equal the same number.
x2, it'll equal the same number.
So now we have  -
- , 30-11= 19.
, 30-11= 19.
 simplified is, 4
 simplified is, 4 .
. 
As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.
I hope this helps you!
