No. If x=1 then 5x squared is 5 and (-5x)squared is 25 so in this case 5x squared is smaller than (-5x) squared. However for numbers larger or smaller than one 5x squared is the same as (-5x) squared e.g. x=2 5x squared = 100 (-5x) squared is still 100.

She is wrong (unless there is a third option again XD) If X is 1 then 5xsq will be 25 while (-5x)sq is also 25 which means they are the same,thus Jennifer is wrong.

She is wrong. (I hope this isn't a 'third option' kind of thing.) If x were to be 5, 5xsq would be 25 while (-5x)sq would also be 25, which shows that the answers are indeed the same. Therefore, Jennifer is wrong

No. If x = 1 then both of the results would be the same, but if x is more than one, then 5x^2 would be smaller. But nonetheless, it shows that 5x^2 is not always smaller than (-5x)^2.

If 'x' is zero, both answers are zero and they are the same.

If 'x' is 5, 5x to the power of 2 means (5X5) X (5X5) = 625 and (-5x) to the power of 2 means (-5 X 5 ) X (-5 X 5) = 625! So both of them are the same. Even If 'x' is 1, 5x to the power of 2 means (5 X 1) X (5 X 1) = 25 and (-5x) to the power of 2 means (-5 X 1) X (-5 X 1) = 25 So, both of them will be the same , No matter what, even if x is zero.

ReplyDeleteI do not agree with Jennifer as:

ReplyDeleteLet x be 1/0

5x^2=5X1/0^2

=infinity

(-5x)^2=(-25)X1/0^2

=infinity

No. If x=1 then 5x squared is 5 and (-5x)squared is 25 so in this case 5x squared is smaller than (-5x) squared. However for numbers larger or smaller than one 5x squared is the same as (-5x) squared e.g. x=2 5x squared = 100

ReplyDelete(-5x) squared is still 100.

no. It is wrong.

ReplyDeleteLet x be 1.

Then, 1x1=1

5x1=5

While -5x1=-5

-5 square= 25

Therefore, (-5x) square is always bigger than 5x square.

No. If X=1 then 5Xsquare will be 25.

ReplyDeleteThus, (-5X)square will also be 25, which means they are equal, so Jennifer is wrong

ReplyDeleteShe is right unless x=0

ReplyDeleteThis is because

Expression 1: 5xsq

Expression 2:(-5x)square(sq)=(-5)sqx(x)sq=25xsq

Compare Ex 1 and 2, Ex 1 is smaller.

No.

ReplyDeleteIf X were 5, 5x square would equal to 25x. (-5x) square would also equal 25x therefore Jennifer is wrong.

She is wrong (unless there is a third option again XD)

ReplyDeleteIf X is 1 then 5xsq will be 25 while (-5x)sq is also 25 which means they are the same,thus Jennifer is wrong.

No.

ReplyDeleteIf x = 1, 5x^2=25

(-5x)^2 = -25

So, 5x^2 is not always smaller than (-5x)^2

yes.

ReplyDeleteif x = 1

5 x 1^2 = 20

-5^2 x 1^2= 27

No,they are equal,

ReplyDeleteX=10

(5x10)sq=2500

-(5x10)sq=2500

No. If x = 1 then both of the results would be the same, but if x is more than one, then 5x^2 would be smaller. But nonetheless, it shows that 5x^2 is not always smaller than (-5x)^2.

ReplyDeleteYES..

ReplyDeletex is a variable --- it can change.

If 'x' is zero, both answers are zero and they are the same.

If 'x' is 5, 5x to the power of 2 means (5X5) X (5X5) = 625

and (-5x) to the power of 2 means (-5 X 5 ) X (-5 X 5) = 625!

So both of them are the same.

Even If 'x' is 1, 5x to the power of 2 means (5 X 1) X (5 X 1) = 25

and (-5x) to the power of 2 means (-5 X 1) X (-5 X 1) = 25

So, both of them will be the same , No matter what, even if x is zero.

Sorry , I do not agree.

DeleteNo.

ReplyDeleteIf x is 1, then, 1 x 1 = 1

5 x 1 = 5

-5 x 1= -5

-5 square = 25

So, (-5x) squared is always bigger than 5x squared.

I do not agree.

ReplyDeleteLet's take x as 10.

5x10=50

50x50=250

And...

-5x10=(-50)

-50x-50=(-100)

So,here you can see that 5x to the power of 2 is greater.

I don't agree

ReplyDeleteTake x as 20

5x20=100

100x100=10000

-100x-100=10000

So they are equal.

I do not agree, because if x = 10, then (5 x 10)^2 = 2500 and ( -5 x 10)^2 = 2500, and so they are equal.

ReplyDeleteI do not agree.

ReplyDeleteScenario 1

If x = 1 ,

5x^2 = 5 x 1 x 1 = 5

(-5 x x)^2 = (-5 x 1 ) x (-5 x 1 ) = 25

5x^2 is smaller.

Scenario 2

If x = 0 ,

5x^2 = 5 x 0 x 0 = 0

(-5 x x )^2 = (-5 x 0 ) x (-5 x 0 ) = 0

Both of their values are 0 thus none of them is smaller.

From the two scenarios above , we can conclude that Jennifer is wrong.
