Answer #1

A negative times a negative is a positive, but in math opposite is gunna mean its positive or negative, in other words the opposite of 2 would be -2. besides that I dont think this problem is solve-able

Answer #2

yeah because X+X=y and X xX=z…if you added them together then it would be more than double x and the person above when they wrote z is negative well why is negative too because they both use X so it would be the same as it not being negative but I think there is a rule about multiplying negatives.

Answer #3

okay…multiplying negatives gives you a positive…you have X xX which is two neg’s so Z is positive…the only way to get a neg is if it were X x why or some other number so sq7 is wrong…look at the problem again…you wrote it wrong.

Answer #4

2X = ‘Y’ X2 = Z

-2X = X2

‘y’ + z = 2X = 2X + X2 = 2X

that doesnt make sense? are you sure that’s the question?

Answer #5

I’m not positive..check it again and see nif you wrote everything out…also it why not why. why is a letter in this case a number…why is a word.

Answer #6

just reading it hurt my head sry I don’t know ://

Answer #7
