## anonymous one year ago A gardener is planning to plant a rectangular vegetable garden during the spring. The rectangle below represents a plan for the garden with a width of x feet. Find the length of the rectangle if the area of a rectangle is x^2 +12x. (hint: factor the trinomial x^2 +12x +0 using the guess and check method.)

Recall that Area of a rectangle is $$\large\rm A=\ell\cdot w$$

3. zepdrix

So we have:$\large\rm x^2+12x=x\cdot\ell$Ya?

4. zepdrix

Try to factor something out of the left side of the equation. Do they have anything in common?
