Show that |3+10| =|3|+|10|

1 answer:

3 0

Since all the numbers are positive, you can take off the absolute value signs. You get 3+10=3+10. Add to get 13=13. Since 13 does equal 13, it does equal each other. Hope this helps! ;)

-2/5n = -30 n= can some one help pleaasee

kirill115 [55]

-2/5n=-30n
multiply both sides by -1 sinc I don' like negatives
2/5n=30n
multipl yboth sides by 5/2
1n=150/2n
n=75n
this is obviously false, the only number that would work is 0 since 0 =0 times 75

n=0

What additional information would you need to prove by the HL theorem?

Butoxors [25]

Answer:

Answer: A $\overline{TM}\cong \overline{OR}$

Step-by-step explanation:

The HL Theorem states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.

Triangles TRO and OMT share the hypotenuse, so the first part of the theorem is met.

Both triangles are right because they have an internal angle of 90°, so the second condition is also met.

Since there is no indication of any leg to be congruent to another leg, we need additional information to prove that both triangles are congruent.

One of these two conditions should be met:

Side TM is congruent to side OR, or

Side MO is congruent to side RT.

From the available options, only the first is correct.

Answer: A $\mathbf{\overline{TM}\cong \overline{OR}}$
