Q. Mateo's home is aa miles away from school. If Lexi's home is twice as far from school as Mateo's home, which of the following expressions represents the distance between Lexi's home and school, in miles?
  1. Understand Relationship Distances: Understand the relationship between the distances. Mateo's home is aa miles away from school. Lexi's home is twice as far from school as Mateo's home.
  2. Write Lexi's Distance Expression: Write the expression for Lexi's distance from school.\newlineSince Lexi's home is twice as far, we multiply Mateo's distance by 22.\newlineDistance for Lexi = 2×a2 \times a
  3. Check Mathematical Errors: Check for any mathematical errors in the expression.\newlineThe expression 2×a2 \times a correctly represents twice the distance of aa, so there are no mathematical errors.
