They are: 29+5 = 34
well, you really have to add up the sides. if you have a 7 by 34 rectangle, you add up like this; 7+7+34+34. it'll be the perimiter around the shape
38
34 = 9 + 25 = 3² + 5²
to work out a mean value you just add all the numbers and divide by how many there are. (6+8+10+11+12+13+13+34)/8=13.38
34 all you have to do is add the numbers up for exaple the sequencs 1 1 2 3 5 8 13 21 if you add zero and one you get one when you add 1 and you get two and so on youget it?
2 tens and 13 ones add up to 33 because 10 +10 +13 = 33.
241
1+34=35, 2+33=35, ....33+2=35, 34+1=35 so 35*34 is 35*34= (30+5)*(30+4) 30*30+5*4 900+20 920 35*34=920/2= 460 if we add up until 34 th answer is 460
21 is the average of 13,16 & 34 because if you add them altogether you get 63 and you divide it by 3 because there is three numbers, you get your average.
13+13+13=39
33, 34 and 35.
