Answer:

(x - 10)(x + 10)

Step-by-step explanation:

x² - 100 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Hence

x² - 100

= x² - 10² = (x - 10)(x + 10)

12080 gallons per month into liters per hour

ryzh [129]

Keeping in mind that, there are 3.78 liters in 1 US gallon and say 30days per month and 24 hours in a day.. then

$\bf \cfrac{12080~\underline{g}}{\underline{month}}\cdot\cfrac{3.78~liter}{\underline{g}} \cdot \cfrac{\underline{month}}{30~\underline{day}}\cdot \cfrac{\underline{day}}{24~hr}\implies \cfrac{12080\cdot 3.78~liter}{30\cdot 24~hr}
\\\\\\
\cfrac{45662.4~liter}{720~hr}\implies 63.42\frac{liter}{hr}$

If AB = 10, BD = 5, and DE= 12, what is the length of BC?

FrozenT [24]

Answer:

BC = 24

Step-by-step explanation:

In the picture attached, the missing triangles are shown:

AB = 10

BD = 5

DE= 12

Then, AD = 10-5 = 5

As a consequence of the "Side Splitter" Theorem:

AD/DE = AB/BC

Replacing with data and solving for BC

5/12 = 10/BC

BC = 10*12/5 = 24
