Let

be an integer. Suppose there is a triangle with legs of length 16 and

. Then by the Pythagorean theorem, the length of the hypotenuse should be

The formulas for Pythagorean triples say that if the legs are integers, then so must be the hypotenuse, because if

and

are integers, then so are

,

, and

.
However,

is not a perfect square trinomial, which means for any integer

, the length of the hypotenuse is not an integer, so such a triangle doesn't exist.
Answer:
2(x-4)=3(x+4)
Step-by-step explanation:
that's easy.
Answer:
-2.1
Step-by-step explanation:
3.4 minus -5.5
The segments AE, EC, AD and DB are in proportion.
Therefore we have the equation:

AE = 4ft, AD = 8ft and BD = 2ft. Substitute:
<em>multiply both sides by 2</em>

I am all yours, just reply with the expression.
