Q. Rewrite in simplest terms: (9x+4)−(9x−8)Answer:
Distribute and Subtract: Subtract the second expression from the first expression by distributing the negative sign across the second set of parentheses. This gives us:(9x+4)−(9x−8)=9x+4−9x+8
Combine Like Terms: Combine like terms by adding or subtracting the constants and the coefficients of the x terms. Since 9x and −9x are like terms and they cancel each other out, we are left with: 4+8
Add Constants: Add the constants together to get the final simplified expression: 4+8=12
