Well adding a negative to a positive is basically subtraction. 2/4+-8/4 would be -6/4. 
This is because 2 isn’t enough to get rid of -8, so we end up with -6.

Oh and -6/4 can be simplified to -3/2.

For the right triangle shown, the lengths of two sides are given. Find the third side. Leave your answer in simplified, radical
sleet_krkn [62]

Answer: c=4\sqrt{2}

Step-by-step explanation:

For this exercise you need to apply the Pythagorean Theorem. This is:

h^2=l^2+m^2

Where "h" is the hypotenuse of the Right triangle and "l" and "m" are the legs.

In this case, you can identify that:

h=c\\\\l=a=4\\\\m=b=4

Knowing these values, you can substitute them into  h^2=l^2+m^2:

c^2=4^2+4^2

Now you must solve for "c":

c=\sqrt{4^2+4^2}

Evaluating, you get:

c=\sqrt{16+16}\\\\c=\sqrt{32}

To simplify the result:

- Descompose 32 into its prime factors:

32=2*2*2*2*2=2^5

- By the Product of powers property, you know that:

2^5=2^4*2

- Make the substitution:

c=\sqrt{2^4*2}

- Finally, knowing that \sqrt[n]{a^n}=a, you get:

c=2^2\sqrt{2}\\\\c=4\sqrt{2}

The sum of 5 consecutive even numbers is 216. What is the third number in the sequence
alexandr1967 [171]

Hello from MrBillDoesMath!

Answer:  NO solution possible!


Steps:

Let "n" be the first even number. We are told that


n + (n+2) + (n+4) + (n+6) + (n +8)  = 216


The third number, the value we want, is boldfaced above.


Simplify the above equation:

5n + ( 2 + 4 + 6 + 8 ) = 216   or


5n +  20  = 216  or

5n = 196


n = 196/5   is NOT an integer value.  This problem, as stated, has no solution.

Regards, MrB
