If x -1/x = 4 then the value of x3+1/x3

-6

Step-by-step explanation:

-1(3) + 1 / 4(3)

-3+1/12

-2/12 = -6

if that's what you mean

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
