Step-by-step explanation:
12 inches make 1 foot
3 feet make 1 yard.
1 yard = 3 feet = 3*12 = 36 inches.
1 yard = 36 inches.
8 yards = 8*36 = 288 inches.
8 yards is not greater or not less than 288 inches.
8 yards is equal to 288 inches.

Step-by-step explanation:
can you rewrite this again?
First of all let x-1=0
x=1
Therefore,
P(x)=2x^4+4x^3-7x^2-kx+9
P(1)=2(1)^4+4(1)^3-7(1)^2-k(1)+9
2(1)+4(1)-7(1)-k+9=0
2+4-7-k+9=0
15-7-k=0
8-k=0
-k=-8
Therefore,k=8
