Which statement best describes the triangle formed by joining the points A(-3,6),B(-11,2),C(-4,-2)

Vikki [24]

Answer:

Isosceles triangle

Step-by-step explanation:

Length of side AB = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

= $\sqrt{(-11+3)^2+(2-6)^2}$

= $\sqrt{64+16}$

= $\sqrt{80}$

= 4 $\sqrt{5}$

Length of BC = $\sqrt{(-4+11)^2+(-2-2)^2}$

= $\sqrt{49+16}$

= $\sqrt{65}$

Length of AC = $\sqrt{(-3+4)^2+(6+2)^2}$

= $\sqrt{1+64}$

= $\sqrt{65}$

Since, AC = BC, ΔABC will be an isosceles triangle.

Find the value if the following expression for the given value of variable. 6t^2 for t = 3

maw [93]

This means it’s 6(3)^2. The PEMDAS process will help in this situation. Since exponents (E) come before multiplication (M), you would raise 3 to the 2nd power first. 3^2 is the same as 3 times 3, which equals 9. Now, you can multiple 6 by 9, which would result with 54. 54 is your answer!
