Answer:

Step-by-step explanation:

Each centimeter is equal to .01 meters

Or 100 centimeters = 1 meter

So if we convert Paula’s painting perimeter of 1.47 meters to centimeters, it would be 147 centimeters.

Now, since each ribbon comes in pieces that are each 25cm, we know are left with an easy division problem 147 divided by 25 or 5.88.

Since she needs the least amount of ribbons that it would take to wrap around the perimeter of the painting, we know it would be 6 because 6x25 = 150cm.

Answer:

Step-by-step explanation:

6)a)

$5\sqrt{27}=5\sqrt{3*3*3}\\\\ =5*3\sqrt{3}\\\\ =15\sqrt{3}$

7a) y² - 5y - 14 = y² -7y +2y - 2*7

= y*(y - 7) + 2*(y - 7)

=(y - 7)(y + 2)

b) Use FOIL method

$(2\sqrt{5}+1)(3\sqrt{5}-1)=(2\sqrt{5}*3\sqrt{5})-((2\sqrt{5}*1)+1*3\sqrt{5})-1*1\\\\ =6*5-2\sqrt{5}+3\sqrt{5}-1\\\\ =30+(-2+3)\sqrt{5}-1\\ \\=29+\sqrt{5}$

c) Rationalize the denominator by multiplying the denominator and numerator by √12

$\frac{6}{\sqrt{12}}=\frac{6*\sqrt{12}}{\sqrt{12}*\sqrt{12}}\\\\=\frac{6\sqrt{2*2*3}}{12}\\\\=\frac{6*2\sqrt{3}}{12}\\\\=\frac{12\sqrt{3}}{12}\\\\=\sqrt{3}$
