Answer:
ddd
Step-by-step explanation:
Divide 5a2 + 6a - 9 into 25a4 + 19a2 - a - 78.
5a^2 -6a +20
-------------------------------------------------
5a^2+6a-9 25a^4 + 0a^3 +19a^2 - 1a - 78
25a^2 + 30a^3 - 45a^2
------------------------------------------------(subtract)
-30a^3 +64a^2 -1a
-30a^3 -36a^2 +54a
-----------------------------------------------(subtract)
100a^2 -55a -78
100a^2 +120a - 180
------------------------------------------------------
- 175a +102
Quotient : 5a^2 -6a+20
Remainder : -175+102

We know from Euclidean Geometry and the properties of a centroid that GC=2GM. Now GM=sin60*GA=
. Hence CM=GC+GM=3*
. Now, since GM is normal to AB, we have by the pythagoeran theorem that:
Hence, we calculate from this that AC^2= 28, hence AC=2*
=BC. Thus, the perimeter of the triangle is 2+4*.
Hence, we calculate from this that AC^2= 28, hence AC=2*
In order to find the average you have to add up all the data values and then find the sum of the data values.
So on average he ran about 82.5 miles.
