So, all you would do is use distribution.
For example: D is .5(x+3) = -3(x-.5)
you would do
.5 times x+3, which equals .5x+ 1.5
So, .5x+1.5=-3x+1.5
because -3*x-.5 is -3x+1.5.
Then, you would just get x by itself.

.5x+1.5=-3x+1.5
add 3 over to .5 = 3.5x;
subtract 1.5 over to 1.5 = 0
now you have 3.5x = 0
divide by 3.5 to get x by itself and you get zero.

x=0

When you substitute it in, you should have them both equal to each other. I hope this helps. :)

Write 2.7 x 10^4 + 120 in scientific notation.
ryzh [129]

Hey there!

2.7 * 10^4 + 120

10^4

= 10 * 10 * 10 * 10

= 100 * 100

= 10,000

2.7 * 10,000 + 120

= 27,000 + 120

= 27,120

Therefore, your answer is. [10,000 * 2.712] because 10,000 * 2.712 is approximately 27,120

Good luck on your assignment and enjoy your day!

Since we know that triangle inequality theorem states that sum of any two sides of a triangle must be greater than third side.

Now let us see if it is true for our given side lengths.

10.6+5.6>4.0

16.2>4.0

Now let us try with another pair.

5.6+4.0>10.6

9.6

We can see that sum of 5.6 and 4 is less than 10.6. Therefore, 10.6 cm, 5.6 cm and 4.0 cm can not be side lengths of a triangle.
