3x + 5
Just combine like terms. The like terms are 2x and x. You can also write x as 1x. The sign is addition so you at 2x + 1x and get 3x. So now you have 3x + 5,you can’t add 3x + 5 cause they aren’t like terms so that’s your answer. :)
Of course not.
-- Take a washable marker, and give your little sister another washable marker.
-- Stand back-to-back in your bedroom, you facing the front wall, and her facing the back wall.
-- When you say 'GO', both of you draw a straight line on the wall.
Then look at the lines.
-- The front and back walls are parallel planes, but it would be
amazing if the two lines are parallel. One could even be a
horizontal line and the other a vertical one . . . definitely not parallel.

Answer:
Step-by-step explanation:
The standard form of a circle's equation is
where h and k are the circle's center and r is the radius. We are told, and we can see, that the center of the circle is (0, 0) so h = 0 and k = 0. The radius, given as 4, goes into the equation squared, so the equation is
which simplifies down to
, choice C.
