D) 4s-10 would be the correct expression. To get the perimeter of the rectangle you would get the expresssion: (s-6)+(s-6)+(s+1)+(s+1), simplified this is equal to 4s-10.
Answer:
6(x + 9) (x + 9)
or

Step-by-step explanation:

Greatest common factor of 6, 108, and 486:
6 x 1 = 6
6 x 18 = 108
6 x 81 = 486
GCF: 6
so:


factors to:
(x + 9) (x + 9)
because:
9 x 9 = 81
9 + 9 = 18
So:
It factors completely too:
6(x + 9) (x + 9)
or

Answer: Area = x² + 6x + 8
Step-by-step explanation:
Area = length x width
Area = (x+2)(x+4)
Area = (x)(x) + (x)(4) + (2)(x) + (2)(4)
Area = x² + 4x + 2x + 8
Area = x² + 6x + 8
I think it is $50.06.
I used a calculator for this.
Hope this helps! :)
