6. Which expression represents the following algebraic statement? twice the difference of a number and 18
O A. 2(n – 18)
B. 2 x n - 18
O C. n(2 x 18)
0 D. 2 x 18-n

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

if e is the midpoint of bd, then bd is 14.
