Answer:
<h3>B. It has infinite solutions</h3>
Step-by-step explanation:
Given the system of equations:
2t + w = 10 ..... 1
4t = 20 − 2w ... 2
From 1:
w = 10-2t ...3
Substitute 3 into 2 to have;
4t = 20 - 2(10-2t)
4t = 20-20+4t
4t = 4t
Let t = k
Substitute t = k into 1 and get w;
From 1: 2t + w = 10
2k + w =10
w = 10 - 2k
<em>k can take any integers. This shows that the solution to the equation is infinite</em>

Answer:
24=12 or false 
Step-by-step explanation:
 
        
             
        
        
        
Positive because it does not go less than 0.
        
                    
             
        
        
        
The quadratic formula is

A = 2
B = -30
C = 108
plug in the values for the equation and you'll get what the factors are
-(-30)+√(-30)²-4(2)(108))/2(2)
and
-(-30)-√(-30)²-4(2)(108))/2(2)
 This will give you your A values
and just round the answers from both of the above equations
