Ms. Scarborough solved x? + 6x - 7 by completing the square in the table below. Identify the missing
steps.
Given the equation
x + 6x - 70
Answer 1:
x? + 6x
= 7
Divide the coefficient of the x
term by two, and square it. Add
this both sides of the equation.
Answer 2:
Convert the left-hand side of the
equation to squared form and
simplify the right hand side.
Answer 3:
Answer 4:
x +3 +4
Solve for x
Answer 5:
Answer 1:

12cm

the answer is d

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
