Can someone pls help with this algebra question?

Factor x^2-8x+9

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

they would have to work 32 hours.
