A snowflake falls 90 feet in 1 minute.
60 ÷ 4 = 15
6 x 15 = 90
The equation that represents the mathematical statement is 2^x + 1 = 21
<h3>How to determine the equation?</h3>
The statement is given as:
Two to the second power +1 equals 21
Equals mean =
So, we have:
Two to the second power +1 = 21
Two to the second power means 2^x, where x is the variable.
So, we have
2^x + 1 = 21
Hence, the equation that represents the statement is 2^x + 1 = 21
