An algebra tile configuration. there are 3 large tiles, 5 tiles each half the size of a large tile, and 8 tiles each one-quarter the size of a large tile. two of the large tiles are labeled plus x squared and 1 is labeled negative x square. two smaller tiles are labeled plus x and 3 are labeled negative x. six of the smallest tiles are labeled + and 2 are labeled minus. which polynomial is represented by the algebra tiles? x2 – x – 4 x2 – x + 4 3x2 – 5x + 8 3x2 – 5x – 8

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
