Answer:

The door has a width of 6.26 feet, with a height of 12.52 feet.

Step-by-step explanation:

You can solve this by taking two pieces of information we're given:

1) the diagonal size of the doorway is 14 feet

2) the height of the doorway twice its width

First lets describe the width and height using the diagonal length. We can do that with the Pythagorean theorem:

w² + h² = 14²

Now we can use the relationship between the width and height to eliminate one variable:

w² + (2w)² = 14²

w² + 4w² = 14²

5w² = 196

w² = 39.2

w ≈ 6.26

So the door has a width of 6.26 feet, with a height of double that, 12.52 feet.

Triple u then divide 3 by the result?

kkurt [141]

Answer:

$beinggreat78~is~here~to~help!$

The equation should look something like this.

$\frac{u(3)}{3}$

Be careful with your use between cubing and multiplying; Cubing is multiplying the number by itself multiple times, while multiplying is like repeated adding, yet much easier.

In this case, if it says triple, I highly recommend multiplying by 3, which is what I did, it only looks different because it is in parentheses.

What have we learned?

<h3>We learned how to write algebraic equations, and some further information on multiplying.</h3>

Anon25 [30]

Answer:

See explaination for the prove of the statement.

Step-by-step explanation:

To establish this prove, lets refer back to what we already know.

We know that "If the set of reactions {d1,d2,d3,......dn} in a vector space V over a field f be linearly dependent, then atleast one of the vectors of the set can be expressed as a linear combination of the remaining others.

Please kindly go to attachment for a detailed step by step explaination of the prove.
