-3(4-9)+6-2(-8+5)
= -3(-5) + 6 - 2(-3)
= 15 + 6 + 6
= 27
(-3*-5) + 6 -2(-3)
= 15 +6 +6 = 27
I have assumed that +6 is a separate added term and not part of (6-2), since there are no parentheses around "6-2"
With parentheses there, the answer would be very different.
To simplify the expression -3(4-9)+6-2(-8+5), we can follow these steps:
Step 1: Simplify the expressions within the parentheses first. We have:
4-9 = -5
-8+5 = -3
Now our expression becomes -3(-5) + 6 - 2(-3).
Step 2: Multiply the values within the parentheses by the coefficients in front of them:
-3 * -5 = 15
-2 * -3 = 6
Our expression becomes 15 + 6 + 6.
Step 3: Add the numbers together:
15 + 6 + 6 = 27
Therefore, the simplified expression is 27.
