Subtract (6x^2-5+3)-(3x^2+8x-4)
A.3x^2-3x+7
B.3x^2+13x-1
C.3x^2+3x-1
D3x^2-13x+7

3x^2 - 13x - 1

Step-by-step explanation:

6x^2 - 5x (i think thats what you meant) + 3 - 3x^2 + 8x - 4

= 3x^2 - 13x - 1

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
