A farmhand is building two pig pens of the same width, but different lengths. If x is the common width, in meters, then the cost of building one pen is 34x^2-4x+22 dollars, and the cost of building the other pen is 22x² + 4x + 46.5 dollars. What's the total cost of building those two pens? A polynomial representing the total cost of building those two pens is dollars​
