In order to find the area you have to multiply length x width 
In this case our length and width are 12cm and 4cm 
So lets multiply those. :P
12 x 4 = 48 cm

Your area = 48cm²

Good Luck! :)

Completing the square follows the principle of taking a x^{2} +bx+c and converting it into (x+ \frac{b}{2})^2+d where d is the 'correctional number' as I like to call it - i.e. the number that converts the expanded bracket into the +c, since the expanded bracket will give us a x^{2} +b.

In this case, 2/2=1 so we have the first part: (w+1)^2.
Expanding this gives us w^2+2w+1. We need c to be 9, so we can just add 8.
Putting this together:

w^2+2w+9=(w+1)^2+8

Now we can solve it more easily.
Rearranging:
(w+1)^2=-8 \\ w+1= +-\sqrt{-8} = +-\sqrt{8}i=+-2 \sqrt{2}i   \\ \boxed{w=-1+ 2\sqrt{2}i\ or\ -1-2 \sqrt{2}i  }

Can someone help me with 8÷2 2/9 −2 11/15
dsp73

Answer:

7/3 or 13/15

Step-by-step explanation:

So you told me that it will be

8/(20/9) -2 11/15 I put parenthesis to make it easier to understand for me

so you must know that a/(b/c)=ac/b si

72/20 -2 11/15 so we work with -2 11/15 which is equal to -30/15 + 11/15 and that will be -19/15 so we have

72/20 - 19/15 we simplify

18/5 - 19/15 so we multiply and divide by 3 in 18/5

54/15 - 19/15 and we add up

35/15 which is equal to

7/3

If this is wrong <u>so we work with -2 11/15 which is equal to -30/15 + 11/15 </u> well it should be so we work with -2 11/15 which is equal to -30/15 - 11/15 and  that equals -41/15 and we get

54/15-41/15

13/15
