Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is given by the formula P = 2 * (length + width).

Front

If a tank is draining at a rate of 15.6 gallons per minute, how much water will be drained after 10 minutes?

Back

After 10 minutes, 156 gallons of water will be drained (15.6 gallons/minute * 10 minutes).

Front

What is the value of x if the length of a rectangle is (2x - 4.7) and the width is (x + 2) with a perimeter of 186 inches?

Back

x = 31.9.

Front

Back

First, distribute 1.5: 27x - 15 = -7x + 29.2. Then, combine like terms to find x = 1.3.

Front
