Answer:
The median height of Sam and his brothers is 135.
Explanation:
First, let's find the age of Sam's brothers:
![B_(1) = 140 cm - 5 cm = 135 cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/3lcjiukwxlzcoq91ks2ex9ncdvccqarm0n.png)
![B_(2) = 140 cm - 7 cm = 133 cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/dqg6qzl2klgokkyaejsjbb7pprcaz37dyt.png)
The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:
133 135 140
Since the middle number is 135, then the median height is 135.
Therefore, the median height of Sam and his brothers is 135.
I hope it helps you!
