notice the arrows on DC and BE, that simply means DC || BE, and therefore the angles ∡D = ∡E and ∡C = ∡B, so the triangles are similar by AA.
check the picture below.
therefore,
BC = x + 4 = 6 + 4 = 10
AC = 10 + 2 = 12.

Answer:
s+7 is numerator of the given expression.
Step-by-step explanation:
We have bee given a rational expression:
is the general representation of the Rational expression where, p is numerator and q is denominator.
So, our given expression is:
We will take the LCM so, given expression can be rewritten as:
(1)
Comparing (1) with general rational expression written above
p=s+7 which is numerator of the given expression.
