we have to find equation similar to

2x=4

Firstly , we can divide both sides by 2

\frac{2x}{2} =\frac{4}{2}

x=2

now, we can multiply both sides by 3

3*x=3*2

we get

3x=6............Answer

Explanation:

Factorizing your equation we get

cot

(

x

)

=

0

so

cos

(

x

)

=

0

we get the following Solutions in the given interval

x

=

π

72

or

x

=

3

π

2

for the second case we get

cot

(

x

)

=

−

1

so

cos

(

x

)

=

−

sin

(

x

)

and we get

x

=

3

π

or

x

=

7

π

Hint:

To get the Solutions of the last equation you can use

√

sin

(

x

+

π

)

=

A cross-shaped pattern is made by arranging four identical rectangles around the side of a square, as shown in the diagram.
const2013 [10]

Answer:

88 cm

Step-by-step explanation:

The side of the square = 6 cm, so the shorter side of each rectangle = 6 cms.

The area of each rectangle =  36 *  1 1/3

= 36 * 4/3 = 48 cm^2

So the longer side of each rectangle = 48 / 6 =  8 cms

Therefore, the perimeter of the whole figure

=  4( shorter sides ) + 8(longer sides)

= 4*6 + 8*8

= 24 + 64

= 88 cm   (answer)
