Answer:
Step-by-step explanation:
We have been given that on a compass, due east is a 1/4 turn clockwise from due north.
Since we know that a compass is in form of a circle and the measure of degrees in a circle is 360 degrees.
To find the number of degrees in a one-fourth turn, we will divide 360 by 4.
Therefore, there are 90 degrees in a 1/4 turn of compass.
For this case we have the following equation:
x2 + 4x = 14
By completing squares we have:
x2 + 4x + (4/2) ^ 2 = 14 + (4/2) ^ 2
Rewriting we have:
x2 + 4x + (2) ^ 2 = 14 + (2) ^ 2
x2 + 4x + 4 = 14 + 4
x2 + 4x + 4 = 18
(x + 2) ^ 2 = 18
Answer:
A. (x + 2) 2 = 18
