9. Y = X2 + 8X +16 A. TWO RATIONAL REAL SOLUTIONS
B. TWO IRRATIONAL REAL SOLUTIONS
C. TWO IMAGINARY SOLUTION
D. ONE REAL SOLUTION

D

Step-by-step explanation:

y = x² + 8x + 16 ← is a perfect square

y = (x + 4)²

To obtain the solutions equate to zero

(x + 4)² = 0 , then

x + 4 = 0 ( subtract 4 from both sides )

x = - 4 ← one real solution

answer: its the third option.

step-by-step explanation:

i just took the test.

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)
