To find out how many inches are in 4 feet, we use the fact that there are 12 inches in a foot. Therefore, we can multiply the number of feet by the number of inches per foot.
The correct expressions that describe how many inches are in 4 feet are:
1. **12 + 12 + 12 + 12** (This adds the inches for each foot.)
2. **4 × 12** (This multiplies the number of feet by the number of inches in each foot.)
The other options do not correctly describe how to calculate the number of inches in 4 feet:
- **12 + 4** does not make sense in this context.
- **12 ÷ 4** does not represent the conversion from feet to inches.
- **4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4** does not represent 4 feet correctly, as it sums 48 instead of the intended multiplication with 12.
Thus, the three options that apply are:
1. **12 + 12 + 12 + 12**
2. **4 × 12**
Unfortunately, only two options are correct based on the provided expressions. The third correct expression is not listed. The addition of the 12's is valid, but the ‘4 + 4 + ...’ is excessive and represents the wrong equivalency.
The best answers are:
- **12 + 12 + 12 + 12**
- **4 × 12**
