Gator · Answer 1

Evaluate what is known

2ab=2 (4) (3) = 24

b^2=3^2=9

3a^2=3 (4^2) = 3 (16) = 48

A. 2a=8

B. 2b=6

C. 4a=16

D. 4b=12

so

2ab+b^2>3a^2-? translates to

24+9>48-?

33>48-?

add? to both sides

33+?>48

minus 33 both sides

?>15

the only choice bigger than 15 is 16 which is C

answer is C
