Answer:
-3, 9
Step-by-step explanation:
x^2 -6x - 27=
= x^2 - 9x + 3x - 27
= x(x - 9) + 3(x - 9)
= (x + 3)(x - 9)
x = -3, x = 9
68% if you take 31 and divide it by 45 you’ll get .68 which you then turn into a percentage
Midpoint = ((x1+x2)/2 , (y1+y2)/2) = (2+14)/2), (1+(-8)/2) = (8,-3.5)
You need to be a bit more specific on the x2. Don’t know if you mean 2x or if you’re saying x squared but I’m assuming 2x so in that case you add the like terms. 4x+2x+2x+x=9x then add the 2
9x+2 is your answer. If you were solving for x and you had an equal sign instead of the addition then your answer would be 9/2 or you could simplify that of course.
9x+2
