When you multiply 5 by 1 you get 5. When you multiply 5 by 2 you get 10. If you keep doing this, you get a list of multiples of 5.
5
10
15
20
25
30
35
40
45
50
All of these numbers end in either 5 or 0. We can do the same with 2's and 10's.
2
4
6
8
10
12
14
16
18
20
For all 2's we can see that they are all even and end with an even number (0,2,4,6,8)
10
20
30
40
50
60
70
80
90
100
For 10's we can see that they all end in 0.
You would multiply a single digit from the second number by every number in the first and repeat the process while adding a zero at the end of the next number.
So you would do the equation 528*9 = 4,752 then for the next one your equation would look something like:
528
x002
-------
10,560
The zero at the end being added on. After you do this with all three numbers you get 158400, 10560, and 4752. Add them together and get 173712 and there is your answer: 173,712
Answer:
![2\sqrt{34}](https://tex.z-dn.net/?f=2%5Csqrt%7B34%7D)
Step-by-step explanation:
We can add a line to create a triangle and a rectangle. The triangle will have side lengths 10 and 6. Furthermore, it will be a right triangle, meaning we can apply the Pythagorean Theorem to find x, the hypotenuse.
![6^2 + 10^2 = x^2\\x = \sqrt{6^2 + 10^2}\\ = \sqrt{136} \\= 2\sqrt34}](https://tex.z-dn.net/?f=6%5E2%20%2B%2010%5E2%20%3D%20x%5E2%5C%5Cx%20%3D%20%5Csqrt%7B6%5E2%20%2B%2010%5E2%7D%5C%5C%20%3D%20%5Csqrt%7B136%7D%20%5C%5C%3D%202%5Csqrt34%7D)
hope this helped! :)
Answer:
x = 10
Step-by-step explanation:
x(x) + x(4) – 5(x) – 5(4) = x(x) + x(–3)
x² + 4x - 5x -20 = x² - 3x
Collect like terms
x² - x² + 4x -5x +3x -20 = 0
2x = -20
Divide through by 2
X = 10
Its basically a factor of the quotient
