Find all of the cube roots of the perfect cube 27/8

Step-by-step explanation:

 3x3x3   = 27    3³

 2x2x2   = 8     2³

so 27/8     =   3³ / 2³      = 3³ x 2^-3

I don't know if I understand the question but I would say it is

3³ / 2³   by   3³ / 2³    by     3³ / 2³

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

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
