Classify triangle aed based on side lengths.
a. scalene
b. isoseles
c. equilateral
d. right

 A. scalene

Step-by-step explanation:

scalene = all three sides have different lengths

isosceles = two of the sides have the same length

equilateral = all three sides have the same length

AE = 5       (2.5 + 2.5)

ED = 3

AD = 7

Since all three sides have different lengths, it is a scalene triangle.

If it is a right triangle, then 3² + 5² = 7²

                                            9  + 25 = 49

                                                  34  ≠ 49   so it is not a right triangle

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
