5(y+2/5)= -13 (please have an explanation)

What situation is an example of an observational study

Atriangle has a side lengths of 18cm, 80 cm and 81cm. classify it as acute obtuse or right?

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
