Simplify the expression. 19m – 4m2 + 4m2

19m

Step-by-step explanation:

19m is the simplified expression:)

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

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)
