Given the expression:
[tex]-7(-15w+21)+3(18-27w)[/tex]
We will simplify the expression as follows:
1) using the distributive property to expand the expression:
[tex](-7)\cdot(-15w)+(-7)\cdot21+3\cdot18+3\cdot(-27w)[/tex]
2) using the commutative property:
[tex]\begin{gathered} 105w-147+54-81w \\ =105w-81w-147+54 \end{gathered}[/tex]
3) Combine the like terms:
[tex]=24w-93[/tex]
So, the answer will be 24w - 93
