Answer:
Tamara  incorrectly factored the whole expression.
Step-by-step explanation:
Note that
- 21x=3·7·x;
- 56xy=2·2·2·7·x·y.
Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.
Thus,
21x+56xy=7x(3+8y).
Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
The minimum is at the vertex of this parabola because it opens up.
Now if (-4, 2) is the minimum then  all the y values on the parabola must be > 2,
But we are given that  y = -3 is on the graph ( the point (6,-3) - that is y < 2 here,
Therefore (-4, 2)  cannot be the vertex .

a = (1+0.2)p
This equation is used to calculate the quantity of lemonade. 
<u>Step-by-step explanation:</u>
Let the quality of lemonade in lans glass be 'a' 
Quantity of lemonade in patricias glass = p ounces
Lan pours 20% more than Patricia 
a = (1+0.2)p
This equation is used to calculate the quantity of lemonade
