Answer:
distance between the two points is 15
Answer:
Step-by-step explanation:
The angles of a quadrilateral have to add up to equal 360. That means that
1x + 2x + 3x + 4x = 360 and
10x = 360 so
x = 36. Then
2x = 72 and
3x = 108 and
4x = 144
Angle A and angle D are opposite angles, as are angles B and C. This is because opposite angles are supplementary.
Answer:
Hope I explain it well!
Step-by-step explanation:
k + a/6 = 3k
well, I am not sure if we need to find the a, or the k, so lets find both!
--
First the a:
k + a/6 = 3k (subtract k)
a/6 = 2k (Multiply by 6)
a = 12k
--
Last, the k:
k + a/6 = 3k (Subtract k)
a/6 = 2k (Divide by 2)
a/12 = k

There you go, I hope you figure it out <3

Step-by-step explanation:
Ana started the work nicely by multiplying out factors to get:\
She multiplied correctly using difference of two squares to get:
Unfortunately: She made a mistake in multiplying she mistakenly got instead of . <em>She left out the coefficient of 2.</em>
Therefore the second step should have been:
The next step will now be:
This simplifies to
Answer:
plus or minus √10 / 4
Step-by-step explanation:
0=-16t^2 +10 becomes easier to solve if we rewrite it as 16t^2 = 10.
Then t^2 = 10/16 = 5/8, and t = plus or minus √(5/8), or
t = plus or minus (√5) / √8), or
t = plus or minus (√5)√8 √5*2√2
------------- = -------------------
8 8
or plus or minus √10 / 4
