Answer:
Jeff is 15 years younger than Joe who is 10
Step-by-step explanation:
Use the ! tool to find the # of combinations.
8!/5! = 40,320/120 = 336
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*

.
X>7/6
Combine like terms
Subtract 2.75x from both sides
Combine like terms
Divide -1.5 from both sides
P=20 this is because you have to get 2 on each side 7.2/3.6 =2 so 20/10=2 2=2
