The side lengths of a triangle are 6, 8 and 12. Is this a right triangle?
Anna [14]

Answer:

No it's not. 6 to the 2nd power + 8 to the 2nd power ≠ 12 to the 2nd power

Step-by-step explanation:

If you square the shorter lengths and add them together, they add up to one hundred

6^2 + 8^2 --> 38 + 64 = 100

Once you square 12 it equals 144

144 does not equal 100. There for it can't be a right triangle. To be a right triangle, it has to have a ratio pf 3: 4: 5.

Ex: 6: 8: 10,  12: 16: 20, etc.

Hope this helps!

Simplify the equation<br> -2x-3=4x-15
Reika [66]
Add -2x to both sides to get 'x' on one side of the equation
-2x-3=4x-15
+2x   +2x
__________
-3=6x-15

add 15 to both sides to isolate 6x
-3=6x-15
+15=6x+15
__________
12=6x

divide both sides by 6 to get 'x' alone
12=6x
/6=/6
_____
2=x

so your answer is 2=x or you can flip it and it will be the same, x=2
