a)
The mathematical expression:
\( P = X + 2X + 4X + X + 3X + X \)
The simplest form:
\( P = 12X \)
The numerical value:
\( P = 60 \)
\( P = X + 2X + 4X + X + 3X + X \)
The simplest form:
\( P = 12X \)
The numerical value:
\( P = 60 \)
b)
The mathematical expression:
\( P = 4X + 2y + 2X + 5y + 4X \)
The simplest form:
\( P = 10X + 7y \)
The numerical value:
\( P = 44 \)
\( P = 4X + 2y + 2X + 5y + 4X \)
The simplest form:
\( P = 10X + 7y \)
The numerical value:
\( P = 44 \)
