Kathy and gale are playing a game with pattern blocks. kathy gives fraction clues and gale uses the clues to determine what one half is. here are kathy's clues: the yellow pattern block is one whole. the green block are three sixths. gale thinks one red pattern block is one half. is gale correct?

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
