The given expression is 
We see from the possible answers they are all in reduced form - variables are grouped together. That means we should also reduce the given expression to see which answer is equivalent to it.
Let's expand the term inside the parentheses first, by multiplying each term inside by the coefficient of the parentheses, -3.
Now let's group terms which have the same variables.
We can see that there are two groups:
Let's evaluate them separately. We just need to reduce each group now, since we've already grouped similar terms.
If we put the groups back together into the expression,
We can see that
. So (D) is the answer. Hope this helped.

Ok, so we do pythagoran theorm so
assume that jason is to the left or right of the anchor
ok
the boat anchor is 172.22 feet so 20 feet above that is 152.22 feet
then the other leg or distance to jeff is 188.82
a²+b²=c²
152.22²+188.82²=c²
23170.9284+35652.9924=c²
58823.9208=c²
sqrt both sides
242.53643190251=c
the distance is about 242.5ft
