The square root of 9 is 3, and 3 divided by 34 and multiplied by 5 is <span>0.44117647058. You would have to use a calculator for this and that's what I did. I hoped I helped!</span>
Answer:
x=2 meters
Step-by-step explanation:
length = 12+2x
width = 6+2x
Area = (12+2x) (6+2x) = 160
Foil
72 + 12x+24x+4x^2 = 160
Combine like terms
4x^2 + 36x +72 = 160
Subtract 160 from each side
4x^2 +36x -88 =0
Divide by 4
x^2 +9x -22=0
Factor
What 2 numbers multiply to -22 and add to 9
11 * -2 = -22
11+ -2 = 9
(x +11) (x-2) =0
Using the zero product property
x=-11 x=2
Since we cant have negative length
x=2
Take 2x and add 1 to equal 113
2x+1=113
