Answer:
The Answer is $9
Step-by-step explanation:
What i did was multiplied 7 times 6 and that equaled 42. They all used 2 dollar off coupons. You asked what was the price of one movie ticket without the coupon, so i added $2 to 7 and got $9
 
        
                    
             
        
        
        
I believe the answer is 3x(3x + 2)
Step-by-step explanation:
 
        
             
        
        
        
X-3y, x=3, y=-2
(3)-3(-2)
(3)+(3*2)
3+6=9
        
             
        
        
        
The product of a <em>complex</em> number and its conjugate is (a + i b) · (a - i b), where a and b are <em>real</em> numbers, and the result for the <em>complex</em> number 2 + i 3 is 13.
<h3>What is the multiplication of a complex number and its conjugate</h3>
Let be a <em>complex</em> number a + i b, whose conjugate is a - i b. Where a and b are <em>real</em> numbers. The product of these two numbers is:
(a + i b) · (a - i b)
Then, we proceed to obtain the result by some algebraic handling:
a · (a + i b) + (- i b) · (a + i b)
a² + i a · b - i a · b - i² b²
a² - i² b²
a² + b²
If we know that a = 2 and b = 3, then the product of the complex number and its conjugate is:

Step-by-step explanation:
13+6=19
you would need to add the negative since it said dropped in temperature and the temperature was already negative.
