Expression given → 4 - 9x + 21
Chang's expression → 4 - 3(3x + 7)
Chang's expression is incorrect because the correct expression is [4 - 3(3x - 7)]
Benjamin's expression → 4 + 3(3x + 7)
Benjamin's expression is incorrect because the correct expression is [4 - 3(3x - 7)]
Habib's expression → 4 + 12x
Habib's expression is incorrect because the correct expression is [4 - 3(3x - 7)]
Correct expression → [4 - 3(3x - 7)]

so the first choice is out.
use the law of cosines to find b
= 
=1681+400-1326.787871
= 754.21219
b= 
b= 27.46292
so the last choice looks good
