Find the value of x and simplify completely.
jok3333 [9.3K]

Answer:

<h2>x=9√10</h2>

Given: A right triangle in which an altitude is drawn from the right angle vertex to the hypotenuse.

To find: 'x' the larger leg of triangle

Solution,

Using let rule for similarity in right triangle:

\frac{leg}{part}  =  \frac{hypotenuse}{leg}  \\ or \:  \frac{x}{27}  =  \frac{3 + 27}{x}  \\ or \: x \times x = 27(3 + 27) \\ or \: x \times x = 81 + 729 \\ or \:  {x}^{2}  = 810 \\ or \:  {x}^{2}  = 81 \times 10 \\ or \:  {x}  =  \sqrt{81 \times 10}  \\ or \: x =  \sqrt{81}  \times  \sqrt{10}  \\ or \: x =  \sqrt{ {(9)}^{2} }  \times  \sqrt{10}  \\  \: x = 9 \sqrt{10}

Hope this helps...

Good luck on your assignment..

How do you write this in numerical expression and in a answer statement
-Dominant- [34]
To write this as a numerical expression, you will think of the different parts of the math story that are occurring and put them together in one math statement.  You have 12 books being ordered that are $9 each AND are paying a $15 shipping charge.  This can be written as 12 x $9 + $15.  There are 2 terms here - these are the 2 parts!  Multiply 12 times 9 first to get $108, then you can add the $15 shipping fee.  You can only add units that are the same, so you must multiply first. Your answer statement is a sentence that gives your final answer in a complete sentence.  For example, the total cost of Lannie's order is $123.

Which expressions are polynomials??
GrogVix [38]

Answer:

Options (1) and (2)

Step-by-step explanation:

Properties of a polynomial,

1). A polynomial having division by a variable can't be defined as a polynomial.

  Example:

   (y² + \frac{x}{1+x})

2). A polynomial can't have a negative exponent.

  Example : (x^{-2}+y-6)

3). Polynomials don't have the radicals.

  Example : y² + x√3

4). A polynomial can't have a fraction exponent.

   Example : x^2+x^{\frac{1}{2}}-1

By these properties, Options (3) and (4) are not the polynomials.

Options (1) and (2) are the correct options.
