We know that
a=9√2
b=9√2
a=b---------- <span>for having both angles of 45</span>
c²=a²+b²-------> (9√2)²+(9√2)²------>(324)-----------> c=√324=18
the answer is the option A 18 inches
In the first series, the summation applies to the whole (2n+3) inside
the parentheses, so the 3 gets summed up 5 times.
But in the second one, the summation only applies to the 2n , so
the 3 is only added after the summation is finished.
The difference between five 3s the first time and one 3 the second time
is your 12 .
