Ab = (7x-6) → b = (7x-6)/a (1)
bc = (12-2x) → b = (12-2x)/c (2)
Since (1) = (2) → (7x-6)/a = (12-2x)/c OR a/c = (7x-6)/(12-2x) (3)
Multiply both numerators of (3) by the SQUARE of their respective denominators;
(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:
ac = (7x-6)(12x-2x) or ac = -14x² + 96x - 72
The correct anwer is option C and option E which are √4<√5<√√55 and √8<2.9<√√9.
<h3>What is inequality?</h3>
Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
The two inequalities √4<√5<√√55 and √8<2.9<√√9. are true.
√4<√5<√√55 → 2 < 2.23 < 7.41
√8<2.9<√√9 → 2.82 < 2.9 < 3
Therefore correct answers is option C and option E which are √4<√5<√√55 and √8<2.9<√√9.

If you convert the fractions to ___/20 then you will see. Here; 2/5 = 8/20. 1/4 = 5/20. I hope this helps.
Step-by-step explanation:
y'=dy/dx=d/dx(4x³+3x²-2x+9)
=(3*4x^(3-1)+2*3x^(2-1)-2*1x^(1-1)+9*0
y'=12x²+6x-2
