Answer:
-0.6
Step-by-step explanation:
12/(-6)(3)+(-2)
12/-18-2
12/-20
-0.6
Hope this helps!
Here's the gist and you can then elaborate:
Proof:
BC = EC, AC = DC (this is given)
angle BCA = angle ECD (vertical angles)
Therefore triangle BCA = triangle ECD (by the side-angle-side theorem).
So therefore BA = ED ( by Congruent Parts of Congruent Triangles are Congruent)
This is not a paragraph proof. You will need to add a little bit more of explanation.
Answer:
9.16
Step-by-step explanation:
by using pythagorean theorem,
given that PQ=4 and NQ = 2×5 = 10
NP²= NQ²-PQ²
= 10²-4²
= 100-16
= 84
NP = √84 = 9.16
Answer:
5.5
Step-by-step explanation:
The lowest temperature ever recorded on Earth is =-94.7
Before this date, the previous record was at= -89.2
the difference between these two extreme temperatures=-89.2-(-94.7)
=-89.2+94.7
=5.5
<u>The difference between these two extreme temperatures is 5.5</u>
