Answer:
the second one 9v+36
Step-by-step explanation:
because with the way it set up it wants you to multiply 9 by everything inside of the parenthesis so 9 times v is 9v and 9 times 4 is 36 thus 9v+36 and you also take the addition symbol from inside the parenthesis.

B. .0151155111555...
Step-by-step explanation:
A.11 integer (rational)
B.0151155111555... non terminating or repeating decimal ( irrational)
C.-14 integer (rational)
D.5/7 fraction (rational)
E.(9.4) 94/10 (rational)
Its a simultaneous equation:
lets make "x" the used games and "y" the new ones
4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156
so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24
Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left
48/9 = how many used ones she can buy = 5. something
she can buy 5 used
