Answer:
x - 231 ≤ 459
Step-by-step explanation:
Given:
Elevation ranges below sea level = 228 ft
Elevation ranges above sea level = 690 ft
Elevation = x
Computation:
Ideal range = [690-228] / 2 = 231
Tolerance range = [690+228] / 2 = 459
So,
x - 231 ≤ 459
The answer is x=3
So c is 3
Answer:
2
Step-by-step explanation:
Answer:
<em><u>E</u></em>
Step-by-step explanation:
transferring the constant
making the coefficient of x^2 to be 1
then add the square of half the coefficient of x
take the square root of both sides
