Remember
a^2-b^2=(a-b)(a+b)
16=4^2
x^4=(x^2)^2
so
16x^4-1=(4x^2)^2-(1)^2=(4x^2-1)(4x^2+1)
and the 4x^2-1 can be further factored
(2x)^2-(1)^2=(2x-1)(2x+1)
factoref rom is
(4x^2+1)(2x+1)(2x-1)
D is answer
That is so easy oh and where are my manners.
My name is Tessadog. I hope you enjoy my answer.
ok so all you have to do is 450 x 3 to find your answer.
Well I may not be 100% because i am more 89.9 % sure so good luck on your test. Please mark me brainiest if i am right.
Tessadog wishes you a good rest of your day and i geuss i am out
Answer: the area multiplies by 9
In other words,
new area = 9*(old area)
------------------------------------------------------
Consider this example:
we have a rectangle that has...
width = 10
length = 12
the area then then 120 since length*width = 12*10 = 120
If we triple each dimension, then we have these new dimensions
width = 30
length = 36
which leads to the new area 36*30 = 1080
Note how the ratio of the areas is 1080/120 = 9
telling us that the new area is 9 times that of the old one
--------------
In terms of algebra
L = old length
W = old width
A = L*W = old area
3L = new length
3W = new width
B = new area
B = (3L)*(3W) = 9*(LW) = 9*A
So B = 9*A tells us that the new area is 9 times the old area
This rule works for any shape. It doesn't have to be a square or a rectangle.
There was 27 people called on Sunday because its
3 x 3 = 9 for Saturday
then 9 x 3 = 27 for Sunday
You can decorate 14 scrapbooks.
7/8=14/16(Double the 7 and 8)
14/16 divided by 1/16
=14
