Question

−6(5−b)+3(−3b−3)−6(−9+b) Раскрыть скобки и упростить выражение

Answer 1

-30+6b-9b-9+54-6b=-9b+15

Answer 2

-6 (5-b)+3 (-3b-3)-6( -9+b)= -30 +6b-9b-9+54-6b= -9b-30-9+54= -9b+15

Answer 3

To simplify the expression −6(5−b)+3(−3b−3)−6(−9+b), we first need to distribute the coefficients to the terms inside the parentheses and simplify:

-6(5 - b) + 3(-3b - 3) - 6(-9 + b) = -30 + 6b - (-9b - 9) + 54 - 6b // distribute the coefficients = -30 + 6b + 9b + 9 + 54 - 6b // distribute the negative sign = 9b + 33 // simplify

Therefore, the simplified expression is 9b + 33.
