Which Pair Shows Equivalent Expressions?

Option (b) is the correct answer as the expression 2\left(\frac{2}{5}x + 2\right) is equivalent to \frac{4}{5}x + 4.

Let's break down each expression to determine their equivalence:

a. 2\left(\frac{2}{5}x + 2\right) = 2\left(\frac{2}{5}x\right) + 1

Expanding the left side: 2 \times \frac{2}{5}x + 2 \times 2 = \frac{4}{5}x + 4

The right side does not match, so option (a) is not equivalent.

b. 2\left(\frac{2}{5}x + 2\right) = \frac{4}{5}x + 4

This matches the expanded left side of option (b), so option (b) is equivalent.

c. 2\left(\frac{2}{5}x + 4\right) = \frac{4}{5}x + 8

This does not match the expanded left side of option (c), so option (c) is not equivalent.

d. 2\left(\frac{2}{5}x + 4\right) = 2\left(\frac{2}{5}x\right) + 8

Expanding the left side: 2 \times \frac{2}{5}x + 2 \times 4 = \frac{4}{5}x + 8

This matches the expanded left side of option (d), so option (d) is equivalent.

In summary, the equivalent pair is option (b).
