Both variables (x) are 3.
4×3=12
12-2=10
16×3=48
48-8=40
3 fits the variable of the missing number.
        
             
        
        
        
Aaaaaaaaaaaaaaaa and bbbbbbbbbbbbbbb
        
             
        
        
        
Answer:
$16 
Step-by-step explanation:
she has $14 now
her parents let her earn 6
so $14 - $6 = $8
so thats what was left over from her allowance. she spent half of her allowance to get to $8 so you double the money

Answer:

Step-by-step explanation:
A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 . 

So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .
<u>★</u><u> </u><u>More </u><u>to </u><u>Know </u><u>:</u><u>-</u>
When we equate this quadratic polynomial with 0 , it becomes a quadratic equation. 
That is , 
 
This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .
