<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>
Answer:
1,006.453 cm
Step-by-step explanation:
1.651 × 103 = 170.053

Answer:
Step-by-step explanation:
it's 12 by 10, 12 x 10 = 120. because it's a triangle, you divide 120 by 2.
120 / 2 = 60. therefore the area of the triangle is 60. I also don't know the unit im supposed to use. is it centimeters? inches? miles?
