The length of a rectangular pool is 3 meters less than twice the width. If the pool's perimeter is 78 meters, what is the width
a) Write an equation to model the problem. Use x to represent the width of the pool.
b) Solve the equation to find the width of the pool. (Note: Include the units, in this case m

this is answer of 144 cubic meters

answer: y=4000x+14000

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
