first speed --- x mph
return speed -- x+16 mph
6/x + 6/(x+16) = 1
times each term by x(x+16)
6(x+16) + 6x = x(x+16)
x^2 + 4x - 96 = 0
(x-8)(x+12) = 0
x = 8 or x is a negative
her first speed was 8 mph
her return speed was 24 mph
check:
6/8 + 6/24 = 1 , that's good!

Answer:
that would be 100449 ! LOL
Step-by-step explanation:
Since 1 yard is 3 feet 38 feet is 38/3 yards which is 12 and 2/3 yards
First, divide the the polygon into two quadrilateral.
Then find the area of both quadrilaterals
The area of the small rectangle = 4 x 3 = 12 square feet
The area of the bigger rectangle = (9 - 3) x 14 = 6 x 14 = 84 square feet
Add both areas:
12 + 84 = 96 square feet
