Question

What is the scale factor expressed by the algebraic representation (2.5x, 2.5y)?

a) 2.5
b) 5
c) 0.4
d) 25

Answer 1

The scale factor expressed by the algebraic representation (2.5x, 2.5y) is 2.5.

Step-by-step explanation:

The scale factor expressed by the algebraic representation (2.5x, 2.5y) is 2.5.

In general, a scale factor represents the ratio of the corresponding lengths or dimensions of two similar figures. In this case, the scale factor of (2.5x, 2.5y) means that each dimension is multiplied by 2.5 to get the corresponding dimension in the original figure.

For example, if (2.5x, 2.5y) represents the dimensions of a rectangle, it means that each side of the original rectangle is enlarged by a factor of 2.5 to get the corresponding side in the new rectangle.
