Given:
Length = x + x + 3 = 2x + 3
Width = 2 + x
Area = length * width
91 ft² = (2x + 3) (2+x)
91 = 4x + 2x² + 6 + 3x
0 = 2x² + 7x + 6 - 91
0 = 2x² + 7x - 85
(2x + 17) ( x - 5)
x = -17/2 or x = 5
Let x = 5 ;
length = 2x + 3 = 2(5) + 3 = 13
width = 2 + x = 2 + 5 = 7
Area = 13 x 7 = 91
Perimeter = 2(length + width)
Perimeter = 2(13 + 7)
Perimeter = 2(20)
Perimeter = 20 feet of fencing
R is equal to 47. U have to add the 9 and 38 to find what R represents. U wellllccccoooommmmmeeee
Answer:
The common ratio is 0.10
Step-by-step explanation:
0.1 x 0.1 = 0.01
0.01 x 0.1 = 0.001
common ratio is the ratio of a term to the previous term.
0.1 is the previous term of 0.01
common ratio = 0.01/0.1 = 0.10
common ratio = 0.001/0.01 = 0.10
Well, for method one the first step we have is distribution, then combining like terms, then property of subtraction, then division. For method two, I'm not entirely sure what they did there. I've never done math like that. Sorry I can't help you out all the way.
