Answer:
First get a common denominator then you divide the numerator then you get your answer
Step-by-step explanation:
Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36
For this case we have the following relationship:
(x / 5280) = (7/100)
From this relationship we must clear the value of x.
Clearing we have:
x = (7/100) * (5280)
Calculating we have:
x = 0.07 * 5280
x = 369.6 feet
Answer:
it does rise in a horizontal distance of 1 mile about:
x = 369.6 feet
