Suppose the distance between x and zero is 6. write an inequality

kvasek [131]

0 < /6/ (absolute value)

That is your inequality since the subject is about the distance away from zero then using common sense you would make the 6 get put in between the 2 absolute value lines ( not trying to be rude, if the explanation seems rude to you im sorry)

Which side lengths form a right triangle

aleksandrvk [35]

Answer:

A and C

Step-by-step explanation:

A right triangle consists of two legs and a hypotenuse.
To find hypotenuse, we use The Pythagorean Theorem
The Pythagorean Theorem = ${a}^{2} + {b}^{2} = {c}^{2}$
two legs meet at a 90° angle and the hypotenuse is the longest side

3 - 4 - 5

6 - 8 - 10

7 - 24 - 25

5 - 12 - 13

are some basic right triangle

(about more, look picture)

<em><u>Just use hypotenuse formula :</u></em>

3 x 3 = 9

4 x 3 = 12

5 x 3 = 15

Option C is correct

${5}^{2} + { \sqrt{6} }^{2} = { \sqrt{31} }^{2}$

Option A is correct

${5}^{2} + {5}^{2} = { \sqrt{50} }^{2}$

But B isn't correct

Hope this helps ^-^
