I do not agree with Jennifer as:Let x be 1/05x^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(-5x) squared is still 100.
no. It is wrong. Let x be 1.Then, 1x1=1 5x1=5While -5x1=-5 -5 square= 25Therefore, (-5x) square is always bigger than 5x square.
No. If X=1 then 5Xsquare will be 25.Thus, (-5X)square will also be 25, which means they are equal, so Jennifer is wrong
She is right unless x=0This is because Expression 1: 5xsqExpression 2:(-5x)square(sq)=(-5)sqx(x)sq=25xsqCompare Ex 1 and 2, Ex 1 is smaller.
No.If 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)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, 5x^2=25(-5x)^2 = -25So, 5x^2 is not always smaller than (-5x)^2
yes.if x = 15 x 1^2 = 20-5^2 x 1^2= 27
No,they are equal,X=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.
YES..x 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) = 25So, both of them will be the same , No matter what, even if x is zero.
Sorry , I do not agree.
No.If x is 1, then, 1 x 1 = 15 x 1 = 5-5 x 1= -5-5 square = 25So, (-5x) squared is always bigger than 5x squared.
I do not agree.Let's take x as 10.5x10=5050x50=250And...-5x10=(-50)-50x-50=(-100)So,here you can see that 5x to the power of 2 is greater.
I don't agreeTake x as 205x20=100100x100=10000-100x-100=10000So 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.
I do not agree.Scenario 1If x = 1 ,5x^2 = 5 x 1 x 1 = 5(-5 x x)^2 = (-5 x 1 ) x (-5 x 1 ) = 255x^2 is smaller.Scenario 2If x = 0 ,5x^2 = 5 x 0 x 0 = 0(-5 x x )^2 = (-5 x 0 ) x (-5 x 0 ) = 0Both of their values are 0 thus none of them is smaller.From the two scenarios above , we can conclude that Jennifer is wrong.
