Answer:

The roots are: (12 + \sqrt{224})/2 and (12 - \sqrt{224})/2

Step-by-step explanation:

We can solve this with the quadratic formula! Plugging it all in, we get (12 +/- \sqrt{144+80})/2 This simplifies to  (12 +/- \sqrt{224})/2. So the roots of our equation are (12 + \sqrt{224})/2 and (12 - \sqrt{224})/2.

Find the length of UC on the attached diagram. Thank you!
ValentinkaMS [17]
<h2>Answer </h2>

The length of UC is 18

<h2>Explanation </h2>

First we are going to find the length of JN; then we are subtracting from it the length of JU plus the length of CN.

We can infer from our picture that JN is 82 + 105, so JN = 187

We can also infer that JU = JH + HU

                                     JU = 22 + 96

                                     JU = 118

We can also infer that CN = 51

Now we can fin the length of UC:

UC=JN-(JU+CN)

UC=187-(118+51)

UC=18

We can conclude that the length of UC is 18.

Help pizzzz The wheel of a bike has a diameter of 26 inches. What is the circumference of the wheel?
larisa [96]
Your answer would be B: 82 inches


To find the circumference of a circle and only given the diameter, you will simply multiply the diameter by pi (3.14) and that will be your answer. You may have to round. Hope this helps!

What is the equation of this graphed line?
o-na [289]

Answer:

y = 2x + 2

Step-by-step explanation:

Notice that this line passes thru (-4, -6) and (2, 6). As we move from (-4, -6) and (2, 6), x increases by 6 and y increases by 12.  Thus, the slope is

m = rise / run = 12/6 = 2.

From the graph we can see that the y-intercept is (0,2).  Thus, the slope-intercept equation of this line is:

y = 2x + 2
