11. Rocco and Biff are two koalas sitting at the

bagirrra123 [75]

Answer:

Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

Step-by-step explanation:

Let the height of Biff's tree be represented by x, so that the height of Rocco's tree is $\frac{x}{2}$ .

Draw a straight line from Rocco's point of view to a point t to the middle of Biff's tree. This line divides x into two equal parts, and the angle is divided into $35^{0}$ each.

By alternate angle property,

Tan $35^{0}$ = $\frac{\frac{x}{2} }{10}$

$\frac{x}{2}$ = Tan $35^{0}$ × 10

= 7.00021

⇒ x = 2 × 7.0021

= 14. 0042

x = 14

Therefore, Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

What’s the least common multiple of x^2-2x-15 and x^2+2x-3?

Ghella [55]

Answer:

$\large\boxed{LCM(x^2-2x-15,\ x^2+2x-3)=(x+3)(x-5)(x-1)}\\\boxed{=x^3-3x^2-13x+15}$

Step-by-step explanation:

$x^2-2x-15=x^2+3x-5x-15=x(x+3)-5(x+3)=(x+3)(x-5)\\\\\\x^2+2x-3=x^2+3x-1x-3=x(x+3)-1(x+3)=(x+3)(x-1)\\\\LCM(x^2-2x-15,\ x^2+2x-3)=(x+3)(x-5)(x-1)\\\\=(x^2-2x-15)(x-1)\qquad\text{use FOIL}\\\\=(x^2)(x)+(x^2)(-1)+(-2x)(x)+(-2x)(-1)+(-15)(x)+(-15)(-1)\\\\=x^3-x^2-2x^2+2x-15x+15\qquad\text{combine like terms}\\\\=x^3+(-x^2-2x^2)+(2x-15x)+15\\\\=x^3-3x^2-13x+15$
