Rewrite in simplest terms:−3(−9a−9)−4(8a−10)

Answer 1

Starting with the given expression: −3(−9a−9)−4(8a−10)

First, we simplify the expressions within the parentheses:

-3(−9a−9) = 27a + 27
-4(8a−10) = -32a + 40

Next, we substitute these simplified expressions back into the original equation:

27a + 27 -32a + 40

Finally, we combine like terms to simplify:

-5a + 67

Thus, the simplest form of the expression −3(−9a−9)−4(8a−10) is -5a + 67.
