Find the unknown measure of the rectangle

19 meters

Step-by-step explanation:

Hope it helps :)

19 square meters

Step-by-step explanation:

Area= L • W

57= ? • 3

So you would divide:

57/3 = 19

Therefore, 19 is our length and unknown measurement.

Area= 19 • 3

Area= 57

Hope this helps, good luck!

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)

    5

y > 1/3x

y < = -x + 4

hope this : )
