A square is changed into a new rectangle by increasing its width by 2 inches and decreasing its length by 2
solniwko [45]

Answer: The area of the square is 64 square inches and the area of the new rectangle is 60 square inches. The square's area is 4 inches larger than the rectangle.

Step-by-step explanation: If a side length of the square measures 8 inches, then its area can be calculated as follows;

Area = L x W

The length and the width both measure 8 inches (all sides of a square are equal in length).

Area = 8 x 8

Area = 64

Also, the the new rectangle is formed by increasing the width of the square by 2 inches (that is 8 + 2 = 10), and decreasing the length by 2 inches (that is 8 - 2 = 6). The area of the new rectangle is calculated as follows;

Area = L x W

Area = 10 x 6

Area = 60

Therefore the area of the square is 64 square inches and the area of the rectangle is 60 square inches. The area of the square is 4 inches larger than that of the rectangle.

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!
