Answer: 15 cm
Step-by-Step Explanation:
Side Length (a) = 5cm
Perimeter = 3a 
Therefore,
= 3a
= 3 * 5
= 15 
Perimeter = 15 cm
        
                    
             
        
        
        
Answer:
the numbers are -20 and 5
Step-by-step explanation:
 
        
             
        
        
        
12 oz = 1.15
24 oz = 2.79
Let's see if 2x12oz is equal, less, or more than the 24oz.
1.15 x 2 = 2.30
2.30<2.79
The 12 oz is a better buy.
        
             
        
        
        
The function in this problem should be: <span>f(x) =x</span>² <span>+ 12x + 6 
y = x</span>² + 12x + 6
y - 6 = x² + 12x 
x² ⇒ x * x
12x ⇒ 2*6*x
missing number is 6² = 36 
y - 6 + 36 = x² + 12x + 36
(x+6)(x+6) ⇒ x(x+6)+6(x+6) ⇒ x² + 6x + 6x + 36 = x² + 12x + 36
y + 30 = x² + 12x + 36
y = (x+6)² - 30
Choice is D. 36,-36
