OR think about it like this(see attatchment)

3x^2 + 3x -6 is what you should get

X+2x^1/2 -63 solve for x
AysviL [449]
You factor this out. So x+2x^(1/2)-63. Factors into (x^(1/2)+9)(x^(1/2)-7). If you distribute it, you can see it gives you your original equation

Marina86 [1]

Answer:

Ribbon can't be enough

Step-by-step explanation:

Markin is making a flag shaped like a square. Each side measures 13 m. He wants to add ribbon along the edges. He has 48 m of ribbon. Does he have enough ribbon? If it is not enough,how much more ribbon needed?

Given :

Side length of square shaped flag = 13 m

Length of ribbon markin has to add along edges = 48 m

To know if the ribbon will enough ; we obtain the perimeter of the square shaped flag ;

4 * side length

4 * 13 = 52 meters

52 > 48

Since the perimeter is greater than the length of ribbon, then ribbon can't be enough
