Answer:
x=4 (solution) x=-14 (extraneous solution )
Step-by-step explanation:
|x+5|=9 -------original equation
Equation can be equal to +9 and -9
x+5 =9 x+5 =-9
x= 9-5 x=-9-5
x=4 (solution) x=-14 (extraneous solution )
for checking
x+5 = 9 x + 5=9
4+5= 9 -14+5=9
9=9 -9=-9
EXPLANATION
The right options are:
(1) All trapezoids are quadrilaterals because trapezoids are four-sided polygons, so they are all quadrilaterals.
(2) All rhombuses are parallelogram because they are quadrilaterals (plane figure, closed shape, four sides) with four equal-length sides and opposite sides parallel to each other.
(4) All squares are parallelogram because they fulfill criteria of being a rectangle because all angles are right angle and opposite sides are equal.
