The first step I would take is
.. Multiply both sides of the equation by 1/4.
_____
You could start by adding 16 to both sides of the equation, to make the left side the square (2x +4)^2.
number one is 280 because 4/2 is 2 + 2 is 4 then you multiply 7 and that is 28 ^ 2 which is 280
You just need to make them all the same common denominator. do you still need help?
I'd say B. but that's only because I divided the number of times he flipped the coin by the number of sides it has, 2, and came up with 246. The closest number on here to that is 231 or B. I hope I helped.
Using an ordered pair is a way of graphing a linear equation on a coordinate plane.
{(-1, 2), (0, 1), (1, 2), (4, 5)}.
