Answer: The width is 
+ 1x -4
Step-by-step explanation:
We know to find the perimeter we have to add the distance around the rectangle.The distance can also be sought as 2 times the length plus times the width.
So as a formula is like P = 2l + 2w where P is the perimeter.
We are given the perimeter so we can plot it into the formula and also plot in the length because it says the length is 3x -1
+8x - 10 = 2(3x -1) + 2w Now we have to solve for w .Break it down
( + 8x -10) = (6x -2 )+ 2w subtract 6x - 2 from both sides
( + 8x -10) - (6x -2) = 2w
( + 2x -8) = 2w now divide both sides by 2
One the left side factor the numerator
= w Now multiply both sides by 2
w =( + 1x-4 )
The width is x^2 + 1x -4
We can find roots by setting f(x) = 0 --> x^4 - x^3 - 13x^2 + x + 12 = 0.
Factoring f(x) to make things easier for us gives us (x - 1)(x + 1)(x - 4)(x + 3), which, equal to 0, gives us the ability to set each set of parentheses = 0.
x - 1 = 0 gives us x = 1.
x + 1 = 0 --> x = -1.
x - 4 = 0 --> x = 4.
x + 3 = 0 --> x = -3.
our roots are x = 1, -1, 4, and -3.

Steps on finding the volume of water :
1. volume . pour enough water from your cup into the graduated cylinder.
2. density . calculate the density by using the formula D=M/V . record the density in (g/m ) ^3 .
3. identify the samples . compare the values for density you calculated to the values in a chart.
Answer:
r = 45 m.
Step-by-step explanation:
pi r^2 = 6358.5
r^2 = 6358.5 / pi
r = √(6358.5 / pi)
= 44.989 m
