Answer:

6\sqrt{5}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{20}

= \sqrt{4(5)}

= \sqrt{4} × \sqrt{5} = 2\sqrt{5}

\sqrt{80}

= \sqrt{16(5)}

= \sqrt{16} × \sqrt{5} = 4\sqrt{5}

Then

\sqrt{20} + \sqrt{80}

= 2\sqrt{5} + 4\sqrt{5}

= 6\sqrt{5}

What is the value of p? (picture below)
Airida [17]

I believe the answer is D) 35°.

We have a 90° angle, and a 55° angle.

(It's 55° because this other angle is supplementary to the angle that equals 125°).

So, 90 + 55 + 35 = 180   Which is the answer we want!

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. How old is Kevin now?
GuDViN [60]
Let k and d be the Kevin's age and the Daniel's age;
We have the equation:
k = 3 + d;
k - 2 = 4( d - 2 );
We have 3 + d -  2 = 4d - 8;
Then, d + 1 = 4d - 8;
9 = 3d;
d = 3.
Finally, k = 6 years.
