What is the least perimeter of a rectangle with an area of 32 square feet

The least perimeter occurs when rectangle is square.

So you can start by taking square root of area; √32

So each side is √32 and there are 4 sides

Hence least perimeter is 4√32 = 16√2 ≈ 22.627.

So you can start by taking square root of area; √32

So each side is √32 and there are 4 sides

Hence least perimeter is 4√32 = 16√2 ≈ 22.627.

Rewrite with only sin x and cos x. sin 2x - cos 2x

Sin2x = 2sinxcosx

cos2x = (cosx)^2 - (sinx)^2 = 2(cosx)^2 -1 = 1- 2(sinx)^2

Any combination you want is here.

cos2x = (cosx)^2 - (sinx)^2 = 2(cosx)^2 -1 = 1- 2(sinx)^2

Any combination you want is here.

Sin2x-cos2x

2sinxcosx-2cos^2x-1

2cos^2x+2sinxcosx-1

I think that's how you do this one.

2sinxcosx-2cos^2x-1

2cos^2x+2sinxcosx-1

I think that's how you do this one.

–12x + 9 = –15x solve for x

Answer:

hi there!

the correct answer to question is: x=-3

Step-by-step explanation:

you move -12x to the other side by adding it on both sides to get: -3x=9 then you divide -3 on both sides to get x=-3

-12x +9 = -15x

+15x +15x

3x +9 = 0

-9 -9

3x = -9

————

3

x= -3

+15x +15x

3x +9 = 0

-9 -9

3x = -9

————

x= -3

BRAINLIEST FOR CORRECT ANSWER!!! A gift in a cubic box with 12 in. edge lengths needs to be wrapped. How many square inches of wrapping paper will be needed to cover the box? 36 in²

72 in²

144 in²

864 in²

The answer is (D 864 in2) hope it helps and have a nice day!

12 * 12 = 144

Cubes have 6 faces.

144 * 6 = 864

You would need 864 in^2 of wrapping paper.

Cubes have 6 faces.

144 * 6 = 864

You would need 864 in^2 of wrapping paper.

Find 19% of 152. A. 0.125 B. 8.00 C. 28.88 D. 2.888 in plato

D. 2.888 in plato the right answer

So we do 152 is 100%

We now substitute a variable for what we are looking for,

If 152 is 100%, so we put it down as 152=100%

Now that x is 19% of the output value, so we can put it down as x=19%

Now we solve two easy equations,

1. 152=100%

2. x=19%

where left sides of both of them have the same units, and both right sides have the same units, now write down this; 152/x=100%/19%

Then we solve the equation; Solution for what is 19% of 152

152/x=100/19

(152/x)*x=(100/19)*x ---- we multiply both sides of the equation by x

152=5.26315789474*x --- we divide both sides of the equation by (5.26315789474) to find x

152/5.26315789474=x

x=28.88

That means that the correct answer is 19% of 152=28.88

Hope This Helps!!!

Travis presented a speech that consisted of a long list of statistics on auto sales in the United States. What technique should he have used to clarify these statistics?

Answer:

Travis should have compared the statistics to something his audience are familiar to and can easily relate with and understand.

S.tep-by-step explanation: The use of statistical data in presenting a speech is a very good and persuasive tool. It gives a qualitative way of supporting and auguing out an idea.

Travis would have used a simple and easily understandable terminology like average to explain and avoid complex ones like variation and standard deviations
