Juanito looked out the window and saw 20 bicycles and skateboards. There were a total 52 wheels. How many of each did he see , s

andriy [413]

Answer:

Let's denote:

x: number of bicycles

y: number of skateboards

Then, we have:

x + y = 20

2x + 4y = 52

=> 2(20 - y) + 4y = 52

=> 2y = 12

=> y = 6 (number of skateboards)

=> x = 14(number of bicycles)

Hope this helps!

If X=3+√8, find X square + 1/x square<br>

irina1246 [14]

Given :-

x = 3 + √8

To find :-

x² + 1/x²

Solution :-

<u>According</u><u> to</u><u> Question</u><u>,</u>

x = 3 + √8
1/x = 1/3-√8
1/x = 1(3+√8)/(3+√8)(3-√8)
1/x = 3+√8/3²-(√8)²
1/x = 3+√8/9-8
1/x = 3 + √8

<u>So </u><u> </u><u>that</u><u> </u><u>,</u>

x² + 1/x²
(x + 1/x)² - 2
( 3+√8+3-√8)²-2
9² - 2
81 - 2
