The triangle with legs x and y is a 30 - 60 - 90 triangle. The patterns of the legs are as follows:

short leg (opposite 30 degree angle) = 1 unit

long leg (opposite 60 degree angle) √3 units

hypotenuse = 2 units.

The pattern is that we double the short leg to get the hypotenuse, or, we go in reverse and take half the hypotenuse to get the short leg.

In the picture we are told the hypotenuse is 16. That makes the short leg as 8, which is x in the picture.

Now we find the long leg and multiply it by √3. This gives us 8√3., the side y.

Thus, x = 8 and y = 8√3.

Factor -24a3b3c3 - 84a4b2c.
sammy [17]

Answer:

-12a³b²c ( 2bc² + 7a)

Step-by-step explanation:

To factorize, we must separate the highest common factors between the products that make up the given expression. To get the highest common factor between the two products,

-24a3b3c3 = -2 * 2 *2 * 3 * a³ *b² *b * c² * c

- 84a4b2c = -2 * 2 *3 * 7 * a³ * a *b² * c

The common elements are  -2, 2, 3, a³, b², c

The product of the common elements

= -12a³b²c

Hence, factorizing

-24a3b3c3 - 84a4b2c = -12a³b²c ( 2bc² + 7a)
