Answer:
x = 3 ± 2
Step-by-step explanation:
given
x² - 6x + 1 = 0 ( subtract 1 from both sides )
x² - 6x = - 1
To complete the square
add (half the coefficient of the x- term)² to both sides
x² - 6x + (- 3)² = - 1 + (- 3)²
x² - 6x + 9 = - 1 + 9
(x - 3)² = 8 ( take the square root of both sides )
x - 3 = ± = ± 2
( add 3 to both sides )
x = 3 ± 2
Answer:
Dimensions → (5 inches × 4 inches)
Step-by-step explanation:
Scale factor used for the drawing by Steffie =
Since, scale factor =
For Steffie,
Actual length of the crate =
=
= 45 inches
Actual width of the crate =
= 36 inches
Since Brian used the scale factor =
Length of the drawing = Actual length × Scale factor
= 45 ×
= 5 inches
Width of the drawing = Actual width × Scale factor
= 36 ×
= 4 inches
Therefore, dimensions of the drawing made by Brian are (5 inches × 4 inches)
