a) Scalene

b) Scalene

c) Isosceles

Step-by-step explanation:

Here, we want to get the type of triangle with the given side lengths

a) 2,5,4

All the side lengths are different, the triangle type is scalene triangle

b) 9,12,13

All side lengths are different, the triangle type is scalene triangle

c) 4,4,9

Two side lengths are equal

The triangle type is an isosceles triangle

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
