Answer:
The dimensions of the field are 65 feet and 715 feet
Step-by-step explanation:
Let the length be L and the width be W.
Given W = 11L
Perimeter of the rectangle = 2(L + W) = 1560 feet
2(L + 11L) = 1560
L = 65 feet
W = 715 feet
Answer:
2= 4 1/6
Step-by-step explanation:
draw the diagram and extend BC to D
draw AD
use the Pythagorean Theorem with triangle ADC
call AD "h"
call DC "x"
h2+x2=102
now use the Pythagorean Theorem with triangle ADB
AD=h, AB=16, DB=(x+9)
h^2+(x+9)^2=16^2
from the first equation get h^2=10^2-x^2
from the second equation get h^2=16^2-(x+9)^2
set the two right sides equal to each other because they both equal h2
10^2-x^2=16^2-(x+9)^2
100-x^2=256-x^2-18x-81
cancel -x2 from both sides
100=256-18x-81
100=175-18x
100-175=-18x
-75=-18x
18x=75
x=75/18
x=4.1666... inches or 4 1/6 inches for the length of DC
6x^5 + 36x^2 + 24x =
6x(x^4 + 6x + 4) <==
