PLEASE HELP URGENT Complete the square to rewrite the following equation. Identify the center and radius of the circle.

You must show all work and calculations to receive credit. x2 + 2x + y2 + 4y = 20

 The Center is (-1,-2)  The Radius is 5

Step-by-step explanation:   x²   + 2x + y² + 4y = 20 To complete the square, leave a space to insert (b/2a)²  That is the square of half of the coefficient of the middle x or y   2/2= 1, 1² = 1  so add to both sides

4/2= 2,  2²= 4 so add that to both sides of the equation too.

X²   + 2x   +1  +   y² + 4y  +4  = (20 +1 +4 )  

X²   + 2x   +1    + y² + 4y  +4   =    (20 +1 +4 )   Add the constants,

Factor the x & y quadratic expressions separately.

(x + 1 )(x + 1 )   +  ( y + 2 )(y +2)  =  25   rewrite the factors as squares

(x + 1 )²  + ( y + 2 )²   = 5²      Then take the square roots of the terms

    √5² =   5  That is the radius of the circle.

solve for x and y to get the coordinate of the center.    

x + 1 =0 x = -1    y + 2 = 0   y = -2    The coordinate of the center is (-1, -2)

the most boring ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
