2 = 120
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
a = (2×3) = 6
b = (3×2) = 6
Substitue into the equation:
a×b=ba−ba+ab
= 6×6 - 6×6 + 6×6
= 36 - 36 + 36
= 36
Therefore, (2*3)×(3*2) = 36
Hope this helps.☺
<span>Let f(n) = 2n + 5. Then we must simply calculate (f1), f(2), ..., (f12). And we have that f(1) = 2*1 + 5 <=> f(1) = 7; f(2) = 2*2 + 5 <=> f(2) = 9; f(3) = 2*3 + 5 <=> f(3) = 11. And so on. It's easy to see that the rest of the results will be 13, 15, 17, 19, 21 and so on. So the summation will be S = 7 + 9 + 11 +... + 29 <=> S = 216</span>
