There is a formula for this:
Time = (Worker1 Time * Worker2 Time) / (Worker1 Time + Worker2 Time)
Time = (12 * 8) / (12 + 8)
Time = 96 / 20
Time = 4.8 Hours

Answer:
Add 81/4 to both sides.
Step-by-step explanation:
x^2 − 9x − 8 = 0
x^2 - 9x = 8
Take the coefficient of the x term: -9
Divide by 2: -9/2
Square it: 81/4
Add 81/4 to both sides.
The answer is the 2nd one because you can only fold this object like this and no other way.
Answer:
Step-by-step explanation:
- Measure of angle J K H + measure of angle J K L = 180 degrees
True.
- Measure of angle J K L + measure of angle J L K + measure of angle K J L = 180 degrees
True. The sum of all interior angles = 180
- Measure of angle J K H = measure of angle J L K =
