Mathematics
1 answer:
topjm [15]3 years ago
6 0

Answer:

The answer is option 3.

Step-by-step explanation:

The steps are :

3 \sqrt{2} (5 \sqrt{6}  - 7 \sqrt{3})

= (3 \sqrt{2} )(5 \sqrt{6} ) - (3 \sqrt{2} )(7 \sqrt{3} )

= 15 \sqrt{12}  - 21 \sqrt{6}

= 15 \sqrt{4 \times 3}  - 21 \sqrt{6}

= 15(2) \sqrt{3}  - 21 \sqrt{6}

= 30 \sqrt{3}   - 21  \sqrt{6}

Find the value of x for which m parallel to n <br> A. 31 <br> B. 33 <br> C. 39 <br> D. 41
olya-2409 [2.1K]
Hello!

We are told that n and m are parallel.
The angle that measures 105 degrees is supplementary with the alternate interior angle of the angle which measures (3x - 18) degrees. Supplementary angles add to equal 180 degrees, so we can make an equation by first finding the measure of the alternate interior angle.

180 - 105 = 75

The alternate interior angle measures 75 degrees, so we can set that equal to 3x - 18 to solve for x since alternate interior angles are congruent.

75 = 3x - 18
93 = 3x
31 = x

Answer:
x = 31

Given the piecewise function shown below, select all of the statments that are true.
timurjin [86]
The <span>given the piecewise function is :
</span>
f(x) = \[ \begin{cases} &#10;      2x & x \ \textless \  1 \\&#10;      5 & x=1 \\&#10;      x^2 & x\ \textgreater \ 1 &#10;   \end{cases}&#10;\]

To find f(5) ⇒ substitute with x = 5 in the function → x²
∴ f(5) = 5² = 25


To find f(2) ⇒ substitute with x = 5 in the function → x²
∴ f(2) = 2² = 4

To find f(-2) ⇒ substitute with x = 5 in the function → 2x
∴ f(-2) = 2 * (-2) = -4

To find f(1) ⇒ substitute with x = 1 in the function → 5
∴ f(1) = 5
================================
So, the statements which are true:<span>
\framebox {B. f(2) = 4} \ \framebox {D. f(1) = 5}</span><span></span>

A dance school charges a registration fee in addition to a fee per lesson. The equation LaTeX: y=30x+25 y = 30 x + 25 represents
klasskru [66]
The equation is 30x + 25
 since the x is with the 30, that would be the cost per lesson, because you would multiply 30 by the number of lessons(x)
