Answer:

46

Step-by-step explanation:

The complete square starting with x^2+14x would be x^2+14x+49, since the square would be (x+7)^2. To make this square perfect, then, you would need to add 46 to make 49 with the 3. Hope this helps!

How do I convert radians to degrees? Is it pi/180 or 180/pi? I get them confused! Thanks
o-na [289]
It could be either one, depending on whether you intend to multiply or divide.

When you convert, just remember that degrees ==> less radians,
and radians ==> more degrees.  Then you can always check the
results, and make sure that you used the right conversion factor
in the right direction.
