Add 10 to both sides, then multiply by -3 on both sides, so:
-n/3-10=0
-n/3=0+10
-n/3=10
n=10x(-3)
n=-30
A solution of a quadratic equation (ax^2+bx+c) is the point at which the parabola crosses the x-axis. We can find this by using the Quadratic formula, which is
. We can solve the equation as follows:
Then we separate the negative from -28 to get:
Then we continue to solve by factoring common terms (-2 and 2). We get the solutions of
. Choice
B matches our first solution.

Answer:56 degrees
Step-by-step explanation: Using Base Angles Theorem, we can conclude that angle x is 180-62*2, which is 180-124, which is 56 degrees.
