Answer:
Question 18: 453,600
Step-by-step explanation:
Answer:
nth term = tn = n� - 2n - 6
if i'm wrong i'm rlly rlly sorry!!
X = 11
angle LKM = angle KLM = angle LMK because it is an equilateral triangle
180/3 = 60
60=3x-27
60-27=3x
33=3x
x=11
From the given triangle, midpoint of AB = ((-2 + 3)/2, (0 + 6)/2) = (1/2, 3) and the midpoint of BC = ((3 + 8)/2, (6 + 0)/2) = (11/2, 3)
Length of the line segment joining points (1/2, 3) and (11/2, 3) is given by
l = sqrt[(11/2 - 1/2)^2 + (3 - 3)^2] = sqrt(5^2) = 5.
Therefore, option A is the correct answer.
D) A theorem is a statement of mathematical truth, while a proof is the series of statements that support the theorem’s claims
