Simplify algebraic expressions to maintain equivalence by collecting like terms involving just two linear variables Tom and Katie are arguing about what term could replace the star in this addition pyramid.
Tom says it could be: \( f \)
Katie says it could be: \( 2 f \)
Who is correct? ![A diagram showing 3 rows of boxes. the bottom row has 3 boxes, containing a star, 3g and 2g from left to right. The next row up contains two boxes, overlapping the joins of the boxes below. Both are empty. The top row is one box, centered over the join of the two below, containing 2f + 8g.]() Only Tom
