Simplify nine square root of two minus three square root of seven plus square root of eight minus square root of twenty eight.

avanturin [10]

Answer:

$11\sqrt{2} - 5\sqrt{7}$

Option (A) is the correct answer.

Step-by-step explanation:

$9\sqrt{2} - 3\sqrt{7} + \sqrt{8} - \sqrt{28}$

Now, $\sqrt{8} = \sqrt{2 \times 2 \times 2} = 2\sqrt{2}$

$\sqrt{28} = \sqrt{2 \times 2 \times 7} = 2\sqrt{7}$

∴ $9\sqrt{2} - 3\sqrt{7} + \sqrt{8} - \sqrt{28}$

= $9\sqrt{2} - 3\sqrt{7} + 2\sqrt{2} - 2\sqrt{7}$

= $9\sqrt{2} + 2\sqrt{2} - 3\sqrt{7} - 2\sqrt{7}$

= $11\sqrt{2} - 5\sqrt{7}$

Therefore option (a) is the correct answer.

6+8x-9=11x+14-3x, can this equation be always, sometimes, or never true.

goblinko [34]

To answer the question above, simplify both sides of the equation. This gives,
8x - 3 = 8x + 14
Next, cancel the term 8x because it appears on both sides of the equation giving,
-3 = 14
That is NOT true. Therefore, the answer is the equation is NEVER TRUE.
