Answer:
7 inches by 7 inches
Step-by-step explanation:
x^2 -10x+25
Factor
What 2 numbers multiply to 25 and add to -10
-5*-5 = 25
-5+-5 = 10
(x-5) (x-5)
The dimensions are (x-5) by (x-5)
Substitute x=12 into the equation
(12-5) by (12-5)
7 by 7
The length is 7 and the width is 7
Answer:
(x - 4)² + (y + 6)² = 5²
Step-by-step explanation:
rearrange the general equation as follows
collect the terms in x and y together and place the constant on the right side
x² - 8x + y² + 12y = - 27
add (half the coefficient of the x/y term)² to both sides
x² + 2(- 4)x + y² + 2(6)y = - 27
(x - 4)² + 16 + (y + 6)² + 36 = - 27 + 16 + 36
(x - 4)² + (y + 6)² = 25
(x - 4)² + (y + 6)² = 5² ← in standard form
