A contractor is hired to build an apartment complex. Each 840-square-foot unit has a bedroom, kitchen, and bathroom. The bedroom

Dennis_Churaev [7]

Answer:

350 sq ft

Step-by-step explanation:

Given that:

840 sq ft area has a bedroom, kitchen and bathroom.

Let the area of bedroom be $x$ sq ft.

Then the area of kitchen will also be $x$ sq ft.

Let the area of bathroom be $y$ sq ft.

As per question statement:

$x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)$

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.

i.e.

$2x+2y=980 ..... (2)$

Subtracting equation (1) from (2):

i.e. (2) - (1):

$y = 140$ sq ft

Putting the value of $y$ in (1):

$2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}$

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>

Identify this problem plssss

JulsSmile [24]

Answer:

The answer is cot(x)

Step-by-step explanation:

<h3>Greetings !</h3>

$\tan(x) \csc {}^{2} (x) - \tan(x)$

Rewrite using trig identity

$- \tan(x) + \csc {}^{2} (x) \tan(x)$

use the Pythagorean idea

$\csc {}^{2} (x) = 1 + \cot {}^{2} (x)$

$- \tan(x) + (1 + \cot {}^{2} (x)) \tan(x)$

simplify

$\cot {}^{2} (x) \tan(x)$

use basic trigonometric identity

$\tan(x ) = \frac{1}{ \cot(x) }$

simplify

$\cot {}^{2} (x) \frac{1}{ \cot(x) }$

gives you

$\cot(x)$

Hope it helps!
