To find out how many inches are in 4 feet, you multiply the number of feet by the number of inches in one foot:
Now let's analyze the options given to find the correct expressions that result in 48 inches:
- This expression correctly computes to 48 inches (4 feet × 12 inches/foot). - This expression results in 3, which is incorrect for finding the number of inches in 4 feet. - This adds up to 48 inches (4 instances of 12). - The calculations here do not add up to 48, as it sums too high. - This expression is incorrect as it sums to 48 but does not use measurements in inches properly based on feet. - This expression results in 60 (48 + 12), which is incorrect for our purpose. - This expression correctly computes to 48 (same as option 1). - This calculates as 40, which is incorrect.
The correct expressions that yield 48 inches are:
Thus, the three expressions that describe how many inches are in 4 feet are:
