For what values of x is the expression 8x/ ( 4 -x ) ( x^2 - 1 )

i think the length is 12 and the width is 17

the answer is d

hope this

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
