That is actually true. Everything thats multiplied by 0 eaquals 0.
Answer:
Option A,
± ![17](https://tex.z-dn.net/?f=17)
Step-by-step explanation:
<u>Step 1: Add 29 to both sides</u>
![n^2 - 29 = 260](https://tex.z-dn.net/?f=n%5E2%20-%2029%20%3D%20260)
![n^2 - 29 + 29 = 260 + 29](https://tex.z-dn.net/?f=n%5E2%20-%2029%20%2B%2029%20%3D%20260%20%2B%2029)
![n^2 = 289](https://tex.z-dn.net/?f=n%5E2%20%3D%20289)
<u>Step 2: Square root both sides</u>
![\sqrt{n^2} = \sqrt{289}](https://tex.z-dn.net/?f=%5Csqrt%7Bn%5E2%7D%20%3D%20%5Csqrt%7B289%7D)

Answer:
segment EG over segment LN equals segment FG over segment MN
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
The corresponding sides are
EF and LM
EG and LN
FG and MN
The corresponding angles are
∠E≅∠L
∠F≅∠M
∠G≅∠N
therefore
EF/LM=EG/LN=FG/MN=3/1
