Answer:
596ft
Step-by-step explanation:
Again, a spreadsheet or suitable calculator makes this short work.
The sum is 184.
_____
The terms being summed are ...
2·3² +3 = 2·9 +3 = 18 +3 = 21
2·4² +3 = 35
2·5² +3 = 53
2·6² +3 = 75
Their total is
21 +35 +53 +75 = 184
16 = k/11
You’re going to need to get K by itself
So you need to multiply 11 on both sides
to remove the denominator of 11
16 x 11 = 176
k/11 x 11 = k
So now the answer would be
176 = k
Hope this helped :)
