Answer:
sqrt3[sqrt3+2sqrt12]=sqrt3[sqrt3+4sqrt3] = sqrt3[5sqrt3= 3x5 =15
 
        
                    
             
        
        
        
27$ because you do 20*15*12 then 3600*0.09 and divide that answer by 12 which is 27
        
             
        
        
        
Answer:

Answer:
x-2x = -3 and x = 3
Step-by-step explanation:
Given the expression
y=x+5.... 1
y-2x=2.... 2
Substituting the first equation into the second we will have;
From 2;
y -2x = 2
x+5-2x = 2
x-2x +5 = 2
x-2x = 2-5
x-2x = -3
-x =-3
x =3
Hence the required equation is x-2x = -3 and x = 3
 
        
                    
             
        
        
        
Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.
<h3>How to find the mean value of a data set?</h3>
The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values 
 x_1, x_2, ..., x_n
, then we get the mean value as:

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm.

mean=
Therefore, If all the scoops are evenly distributed, they would all be 3.8 cm tall.
