Calculate the approximate length of each side of ΔABC with coordinates A(1, 1), B(4, 4), and C(5, 1). Then, classify the triangle as scalene, isosceles, or equilateral. AB ≈ _

BC ≈ _

AC ≈ _

So, ΔABC is _

Step-by-step explanation:

Line AB = sqrt18 = 4.24

Line BC = sqrt10 = 3.16

Line AC = 4

Since the triangle cannot be isosceles or equilateral, the best option here is scalene.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
