The perimeter of a rectangle is 128 cm. The width is 3 times the length. What are the dimensions of the rectangle?

Step-by-step explanation:

Perimeter of the rectangle= 128

Let, the Length of the rectangle be 'L'

Width=3*L

Perimeter of the rectangle =2(Length+width)

            Width=4*L= 4*16= 64

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
