Ok so its 8 `1&8 2&7 3&6 4&5 and then all of those numbers reversed
18 27 36 45 and 81 72 63 54
The answer is 39, jk=18 because j multiplied by k is 18 and then i added 3 and i got 21, then k (6) multiplied by 3 is 18, so then i added 21 and 18 and i got 39
The area of a paralellogram is bh
each dimention is multiplied by n
b turns to bn
h turns to hn
bh turns to (bn)(hn) or bnhn or bhn²
expression is bhnn or bhn² or bhn^2 (depends if the program will let you enter the exponent)
You would multiply it by 4
4(3x^2 +2 )
12x^2 +8
The answer would be the second choice. 4:5
