X2y4(x2 - 16) - 9y4(x4 - 16) how do i simply this?

e-lub [12.9K]

Answer:

The simplified expression is given as

$8x^2y^4(17x^2-2)$

Step-by-step explanation:

step one:

Given the expression

$x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)$

step two:

First, let us open the bracket we have

$x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)\\\\x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\$

step three:

collect like terms we have

$x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\x^4y^4-9x^4y^4+144x^4y^4-16x^2y^4\\\\-8x^4y^4+144x^4y^4-16x^2y^4\\\\136x^4y^4-16x^2y^4\\\\\\$

step four:

we can now factor out $8x^2y^4$ we have

$8x^2y^4(17x^2-2)$

Haley measured the distances between her house and two of her friends' houses. ellen's house is 1.41 miles away from haley's, an

Arada [10]

Answer: Ellen's house is farther away by 898 feet.

Step-by-step explanation:

Given: The distance between Haley's house and Ellen's house = 1.41 miles

We know that 1 mile = 5,280 feet

Then, $1.41\text{ miles}=1.41\times5,280\text{ feet}=7,444.8\text{ feet}$

The distance between Haley's house and Dirk's house = 6,547 feet

Clearly, 6,547<7,444.8

And $7444.8-6547= 897.8\approx898$

Therefore, Ellen's house is farther away by 898 feet.
