What are the solutions to the quadratic equation 2x2 + 10x - 48 = 0? A. x= -6 and x = 8

B. x = -4 and x = 6

C. X=-8 and x = 3

D. x= -8 and x = 2 ​

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the answer is simply just 6n add the two together as they have an n
