Matt has a block. he uses one of the flat surfaces of the block to trace a triangle what type of solid figure is matt’s block?

Pyramid because the pyramid is the only type of block that has triangular sides

Sorry can't answer that question

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
