Recognize that both 144 and 256 are perfect squares; their sqrts are 12 and 16 respectively.  Therefore, 

          144        12      3
sqrt{  ------ } = ----- = ----
          256         16     4

Actually, there are negative roots as well as positive ones here; so (for example) write -12/16 as well as +12/16.

so the best answer is B.</span>

What is the value of n?
morpeh [17]

Answer:

n = 28 degree

Step-by-step explanation:

2n + 17 + 2n - 5 + 2n = 180 degree (sum of interior angles of a triangle)

6n +12 = 180

6n = 180 - 12

n = 168/6

n = 28 degree

Solve the equation.<br> -3x +.1 + 10x = x + 4<br> N<br> olu<br> R<br> X =<br> 18
zheka24 [161]

Answer:

Hence after solving the given equation we get <em>x = 13/20.</em>

Step-by-step explanation:

<em>Given:</em>

<em>-3 x + 0.1 + 10 x = x + 4</em>

<em>-3 x + 10 x - x = 4 - 0.1</em>

<em>6 x = 3.9</em>

<em> x = \frac{3.9}{6}</em>

<em>x = \frac{1.3}{2}</em>

<em>x = \frac{13}{20}</em>
