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 .
Answer:
-2, -3
Step-by-step explanation:
-2*-3=6
-2+-3=-5
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
