Complete the square:
x^2 +6x +c
2 answers:
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
<u> So c= -9</u>
Answer:
c=√(c+9)-3
Step-by-step explanation:
x²+6x=-c
x²+6x+(3)²=-c+(3)²
(x+3)²=-c+9(find the square root of both sides)
√(x+3)²=√(c+9
x+3=√(c+9)
c=√(c+9)-3

Triangle:
A = 3 x 9 x 1/2 = 13.5
Large rectangle (center):
A = 9 x 12 = 108
Medium rectangle:
A = 4 x 6 = 24
Small rectangle (bottom):
A = 4 x 2 = 8
Figure:
A = 13.5 + 108 + 24 + 8 = 153.5 square feet
Hope this helps! :)
7 because 42 divided by 6= 7 and length times width = perimeter
