Find three consecutive integers that have a sum of -39.

-14, -13, and -12

Step-by-step explanation: When thinking about consecutive numbers we think about numbers that are right next to each other. We also know that the word "sum"means adding by our signal words.

Since the sum of our three consecutive integers is -39, we can set up an equation to represent this.

X + X + 1 + X + 2 = -39

3x + 3 = -39

      -3     -3

3x = -42

÷3     ÷3

X = -14

X ⇒ -14

X + 1 ⇒ -13

X + 2 ⇒ -12

Therefore, our three concussive integers are -14, -13, and -12.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
