1)25а-40+2а=27а -40

2)12+4х-20=4х-8

Answer 3

To simplify the expressions, let's apply the order of operations (PEMDAS/BODMAS):

1. 25a - (5 + 2a) * 8: Start by simplifying the parentheses: 25a - (5 + 2a) * 8 = 25a - (5 * 8 + 2a * 8) = 25a - (40 + 16a) = 25a - 40 - 16a = (25a - 16a) - 40 = 9a - 40

   Therefore, the simplified expression is 9a - 40.

2. 12 + 4(x - 5): Distribute the 4 to the terms inside the parentheses: 12 + 4(x - 5) = 12 + 4x - 20 = (12 - 20) + 4x = -8 + 4x

   Thus, the simplified expression is -8 + 4x.
