Answer:

Step-by-step explanation:

so let’s say x is the length. Then the width will be 3x-4. You add them together and multiply by two. The perimeter is 72 so the equation equala 72.

Equation:

(x+3x-4)*2=72

(4x-4)*2=72

8x-8=72

8x=80

x=10

length:10

width:26

Help please any One who can solve this equation? ☺

If y varies directly with x, that means they change at proportion rates. We can define their relationship using a constant k.

y = kx

Plug in what we know to find k.

-3 = 5k

k = -3/5

So:

y = -1 * (-3/5)

y = 3/5
