Factor Completely x^4-2x^2y^2+y^4

12345 [234]

<h3>Answer :</h3>

$\bf (x+y)^2(x-y)^2$

==============

<h3>Solving Steps:</h3>

===============

$\rightarrow \sf x^4-2x^2y^2+y^4$

<u>breakdown</u>

$\rightarrow \sf x^4-x^2y^2-x^2y^2+y^4$

<u>factor common term</u>

$\rightarrow \sf x^2(x^2-y^2)-y^2(x^2-y^2)$

<u>collect in groups</u>

$\rightarrow \sf (x^2-y^2)(x^2-y^2)$

<u>apply difference between two square method:</u> x² - y² = (x+ y)(x-y)

$\rightarrow \sf (x+y)(x-y) (x+y)(x-y)$

<u>simplify</u>

$\rightarrow \sf (x+y)^2(x-y)^2$

Thirteen unit cubes are taken from the tousand cube write a fraction and a decimal to represent how many unit cubes are left

Neko [114]

The number of unit cubes left after taken 13 unit cubes from the thousand unit cubes expressed as a fraction and decimal is; 987/1000 and 0.987 respectively.

<h3>What is the number of unit cubes left when thirteen unit cubes are taken away from a thousand expressed as a fraction and decimal?</h3>

It follows from the task content that the description goes thus; Thirteen unit cubes are taken from the thousand cube.

Hence, the number of unit cubes left is; 1000 - 13 = 987.

Consequently, when expressed as a fraction of the whole, we have; = 987/1000 and when expressed as a decimal, we have; 0.987.

Building A is 170 feet shorter than building B. The total height of the two buildings is 1520 feet. what is the height of each b

Drupady [299]

Answer:

Step-by-step explanation:

If A is 170 less than B, than the equation for that is:

A = B - 170 (1) where the word "is" means equals and less than is subtraction.

If the total of A + B is 1520, then

A + B = 1520 (2). Sub equation (1) into equation (2):

(B - 170) + B = 1520 and

2B - 170 = 1520 and

2B = 1690 so

B = 845. Building B is 845 feet tall and Building A is

A = 845 - 170 (this is equation (1) with the height of B subbed in) so

A = 675 feet

675 + 845 should equal 1520 according to our equation. And of course it does.
