To simplify the expression \( 25(34p + 56w) + 15(12p - 623w) \), we will start by using the distributive property.
-
Distribute 25 in the first part:
\[ 25(34p) + 25(56w) = 850p + 1400w \]
-
Distribute 15 in the second part:
\[ 15(12p) + 15(-623w) = 180p - 9345w \]
Now we can combine both parts:
\[ 850p + 1400w + 180p - 9345w \]
-
Combine like terms (the \( p \) terms and the \( w \) terms):
For \( p \): \[ 850p + 180p = 1030p \]
For \( w \): \[ 1400w - 9345w = -7945w \]
-
So, the simplified expression is:
\[ 1030p - 7945w \]
Thus, the final answer in its simplest form is:
\[ \boxed{1030p - 7945w} \]
