Use the distributive property to multiply 9 by 3 and 3 by 5n to get that answer.
Answer:
Length of garden will be 30 metres.
Step-by-step explanation:
Let the Width of garden be x metres.
then,
Length of garden will be (x+6) metres.
Area = Length × Breadth
720 = x X (c+6)
720 = x²+6x
0 = x²+6x-720
As we can see above equation is a quadratic equation in the form of ax²+bx+C.
so,
![= \frac{ - b ± \sqrt{{b}^{2} - 4ac} }{2a} \\ = \frac{ - 6 ± \sqrt{{6}^{2} - 4 \times 1 \times - 720} }{2} \\ = \frac{ - 6 ± \sqrt{36 + 2880} }{2} \\ = \frac{ - 6 ± \sqrt{2916} }{2} \\ = \frac{ - 6 ± 54}{2}\\= \frac{-6+54}{2} ... \frac{ - 6 - 54}{2} \\ = \frac{48}{2} ... \frac{ - 60}{2} \\ = 24... - 30](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B%20-%20b%20%C2%B1%20%20%5Csqrt%7B%7Bb%7D%5E%7B2%7D%20-%204ac%7D%20%20%7D%7B2a%7D%20%20%5C%5C%20%3D%20%20%20%5Cfrac%7B%20-%206%20%C2%B1%20%20%20%5Csqrt%7B%7B6%7D%5E%7B2%7D%20-%204%20%5Ctimes%201%20%5Ctimes%20%20-%20720%7D%20%20%7D%7B2%7D%20%20%5C%5C%20%3D%20%20%20%20%5Cfrac%7B%20-%206%20%C2%B1%20%20%5Csqrt%7B36%20%2B%202880%7D%20%7D%7B2%7D%20%20%5C%5C%20%20%3D%20%20%20%5Cfrac%7B%20-%206%20%C2%B1%20%20%5Csqrt%7B2916%7D%20%7D%7B2%7D%20%20%5C%5C%20%20%3D%20%20%20%5Cfrac%7B%20-%206%20%C2%B1%2054%7D%7B2%7D%5C%5C%3D%20%5Cfrac%7B-6%2B54%7D%7B2%7D%20...%20%5Cfrac%7B%20-%206%20-%2054%7D%7B2%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B48%7D%7B2%7D%20...%20%5Cfrac%7B%20-%2060%7D%7B2%7D%20%20%5C%5C%20%20%3D%2024...%20-%2030)
One of the Roots of the Quadratic equation is 24 and other is -30.
And as we know width of any garden cannot be negative so the width of garden will be 24 metres.
As we got the width,
adding 6 to it will give us the Length,
So,
24 metres + 6 = 30 metres.
Length of the garden is 30 metres.

Answer: 45%
Step-by-step explanation:
Discount = original price - selling price
= $9.20 - $5.06
Discount = $4.14
Discount Percent = discount x 100 / original price
= $4.14 x 100 / $9.20
= $414 / $9.20
Therefore,
Discount Percent = 45%
I hope it helps you.
