What is the simplified form of the following expression 7(3sqrt 2x) - 3(3sqrt 16x) - 3(3sqrt 8x)

zimovet [89]

Answer: $\bold{3\sqrt{2x}-36\sqrt x}$

<u>Step-by-step explanation:</u>

$7(3\sqrt{2x})-3(3\sqrt{16x})-3(3\sqrt{8x})\\\\=21\sqrt{2x}-9\sqrt{16x}-9\sqrt{8x}\\\\=21\sqrt{2x}-9\cdot 4\sqrt x-9\cdot 2\sqrt{2x}\\\\=21\sqrt{2x}-36\sqrt x-18\sqrt{2x}\\\\=(21-18)\sqrt{2x}-36\sqrt x\\\\=3\sqrt{2x}-36\sqrt x$

Answer:

55.36 m

Step-by-step explanation:

The Pythagorean theorem relates the side lengths of a right triangle. For legs 'a' and 'b', and hypotenuse 'c', it tells you ...

c² = a² +b²

For this figure, that means ...

?² = 19² +52² = 361 +2704 = 3065

? = √3065 ≈ 55.36 . . . . meters

The missing side length is about 55.36 meters.

She would end up with:
1) A total of 15 inches of dowel (or 1' 3" - A foot and 3 inches)
2) Pieces that are 2 1/2" (inches) long.
