lyudmila [28]
The length, l, is 2 more than twice the width, w.
l= 2w+2 (2 more than twice w)
In a rectangle, we have two of the same lengths and two of the same widths.
2l+2w=34
Divide by 2 on each side.
l+w=17
We remember that l is 2w+2
Substituting that back in we get,
2w+2+w=17
3w+2=17
3w=15
w=5
We sub w back into l+w=17
l+5=17
l=12
The dimensions are 5 by 12 inches.

= (7 2/3) / (1 1/3)

= (23/3) / (4/3)

= 23/3 * 3/4

= 69/12

= 23/4

= 5 3/4

Tan x + tan 2x = 0
choli [55]

stated method in question is wrong!

<u>Step-by-step explanation:</u>

We need to find the general solution of x ! for the equation tan x + tan 2x = 0

⇒  tan x + tan 2x = 0

⇒  (tan x + tan 2x)-tan2x = 0-tan2x

⇒  tan x = -tan2x

Now , we know that tan(\pi -2x) = -tan2x

⇒  tan x = -tan2x

⇒  tan x = tan(\pi -2x)

Now , we know that TanA = TanB \\A=B

⇒  tan x = tan(\pi -2x)

⇒  x = \pi -2x

⇒  3x = \pi

⇒  x = \frac{\pi}{3}     ......(1)

General solution of Tan x is : x = n\pi + \alpha , \

Here , from equation (1) we get  \alpha =\frac{\pi }{3} . Hence general solution is :

⇒ x = n\pi +\frac{\pi }{3} .Therefore , stated method in question is wrong!

Which reasons could be used to prove that a parallelogram is a rhombus
Iteru [2.4K]

GOOGLE TIME- *cough *cough*

A rhombus is a special case of a parallelogram, because it fulfills the requirements of a parallelogram: a quadrilateral with two pairs of parallel sides. It goes above and beyond that to also have four equal-length sides, but it is still a type of parallelogram.
