True [87]

Answer:

The points form a equilateral triangle of side 5.78 units.

Step-by-step explanation:

The length of the sides of the triangle is calculated using the distance formula.

The distance between the points (x₁,y₁) and (x₂,y₂) is

$d= \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

Now,

AB = $\sqrt{(11.11-14)^{2}+(15-10)^{2}}=\sqrt{8.3521+25} = \sqrt{33.3521}=5.78$

BC = $\sqrt{(8.22-11.11)^{2}+(10-15)^{2}}=\sqrt{8.3521+25} = \sqrt{33.3521}=5.78$

CA = $\sqrt{(8.22-14)^{2}+(10-10)^{2}}=5.78$

The length of the sides of the triangle is 5.78. All the sides are equal in length. It is an equilateral triangle.

Nina is 10 years younger than Deepak. Deepak is 3 times as old an Nina. Which system of equations can be used to find d, Deepak’

nevsk [136]

The answer would be the first choice which is d = n + 10, d = 3n. Deepak is 10 years older than Nina, so knowing this, the equation cancels out B and D. And Deepak is 3 times Nina's age, not Nina's age is three times Deepak's. It is not the other way around.
