Answer:
The standard from of the expression is:
Step-by-step explanation:
Here the given expression is :
Now, the standard form of a circle is given as :
Here, (h,k) = Coordinates of Center, r = Radius
Also, use the algebraic identity:
Now, converting the given expression in the standard form, we get:
Add 2 on both sides of the equation, we get:
So, here the standard from of the expression is:
Center coordinates here are (h,k) = ( -1 ,1) and Radius = 2 units

Answer:
A. positive -positive = positive
<span>x is the total number of liters of orange juice and water combined. 80% of the mixture is pure orange juice which means 20% of it is water. Therefore, x 20/100 = 1 is the equation in single variable that can be used to find x. and 20/100 is 1/5 so there are 5 total liters in all and 5-1 is 4, so there are 4 liters of orange juice in the can. Hope this helps :)</span>
