If ab= 7x-6 and bc= 12-2x. Then what does ac equal?
ra1l [238]
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

8..................................
ser-zykov [4K]

Answer:

The answer is 2x^{3}y^{-2}\sqrt{6}

Step-by-step explanation:

∵ √24 = 2√6

∵ \sqrt{x^{6}}=(x^{\frac{1}{2}})^{6}=x^{3}

∵ \sqrt{y^{-4}}=(y^{\frac{1}{2}})^{-4}=y^{-2}

∴ \sqrt{24x^{6}y^{-4}}=2x^{3}y^{-2}\sqrt{6}
