Question

Sophia was asked to find the original dimension of a reduced hexagon. Sophia found that the enlarged hexagon's dimensions were just 6 more than the original hexagon, thus x = 3. What was Sophia's error?

Answer 1

A and C

Explanation:

Sophia was asked to find the original dimension of a reduced hexagon.

A smaller hexagon has a top side length of 1.2 inches and bottom side length of x inches. A larger hexagon has a top side length of 7.2 inches and bottom side length of 9 inches.

Sophia found that the enlarged hexagon’s dimensions were just 6 more than the original hexagon, thus x = 3. What was Sophia’s error?

Sophia should have found the number the dimensions were multiplied by.

Sophia should have divided 9 and 6 .

Sophia should have set up a proportion to solve for x.

Sophia should have multiplied 7.2 and 1.2.

Sophia is correct and did not make an error.
