Question

1. Expand to write an equivalent expression: - 1/2 (-2x+4y)

2. Factor to write an equivalent expression: 26a−10

Answer 1

Answer:

$1)x - 2y$

$2)2(13a - 5)$

Step-by-step explanation:

$1) - \frac{1}{2} ( - 2x + 4y) \\ \frac{2x}{2} - \frac{4y}{2} \\ = x - 2y$

$2)26a - 10 \\ = 2(13a - 5)$
