Work out 50 divided by [6-4]
BaLLatris [955]
This is pretty simple. This requires the order of operations. So for the order of operations, it basically tells you the order on how you solve operations.

The first order is brackets, the second one is division, the third one is multiplication and the fourth one is addition or subtraction.

For this case, you have { 6-4 }. 6-4 is on brackets, so you have to solve it first. The answer is 2.

After that, you can divide 50 by 2, which gives you 25.

I hope I have been helpful. Good luck! :)

Please can you help me, it would be greatly appreciated.

Answer:

20 cm^2.

Step-by-step explanation:

If the scale factor is 2 each of the sides of the figure will be increased by a factor 2.

So each side will have a length of 2 * 1 = 2 centimeters.

It will consist of 5 squares of dimension 2*2 =  an area of 4 cm^2

So the area of the new cross  is 5*4 = 20 cm^2.

We can also calculate the area directly by multiplying  by 2^2 ( the scale factor)squared.)

The original area = 5 so the area of the enlarged figure = 5 * 2^2 = 20 cm^2.

HELP ASAP PLEEEEEEEEEAAAASSSSE GIVING BRAINLIEST

Answer:

It can be decomposed into the following simplest shapes:

TWO RECTANGLES AND ONE TRIANGLE  

Step-by-step explanation:

You can observe in the picture attached that it can be decomposed into the following simplest shapes:

Two Rectangles.

One Triangle.

Because,

The area of the a rectangle can be found with:

A= lw

Where "l" is the length and "w" is the width.

You can identify in the picture that:

lA: 14 ft

Wa: 13ft -7ft= 6ft

1b= 20 ft

wb= 7ft

So, Substituting the values, you get that the areas of the rectangles A and B are:

Aa: (14ft) (6ft)= 84ft²

Ab: (20ft) (7ft) = 140ft²

The formula for the area of a triangle is:

A= bh/2

Where "b" is the base and "h" is the height.

In this case:

b= 20ft- 14ft= 6ft

h= 6ft

Then, its area is:

Ac =(6ft) (6ft)/2

which iis 18ft²

Then, it will bring the total area of carpet that Valerie needs:

At= Aa+ Ab+ Ac

At= 84ft² + 140ft² + 18ft²

At= 242²

If cosx+sinx=sqrt(2)cosx then show that cosx-sinx=sqrt(2)sinx
Stella [2.4K]
Hello,

We suppose cos (x)≠0 and sin(x)≠0

cos(x)+sin(x)=√2 cos(x)
==>1+tg(x)=√2
==>tg(x)=√2-1
==>1/tg(x)=1/(√2-1)
==>cos (x)/sin(x)= √2+1
==>cos(x)=sin(x)+√2*sin(x)
==>cos(x)-sin(x)=√2 sin(x)
