Step-by-step explanation:
Polygon WXYZ has vertices W(-1.5, 1.5), X(6, 1.5), Y(6, -4.5), and Z(-1.5, -4.5).
Find the slopes of all sides:
- horizontal line
- slope undefined, so the line is vertical
- horizontal line
- slope undefined, so the line is vertical
Vertical and horizontal lines are perpendicular, so all angles W, X, Y and Z are right angles. Hence, quadrilateral WXYZ is a rectangle

Answer:
-2
Step-by-step explanation:
f[g(x)
=f(3x^2+6x-2)
=2 (3x^2+6x-2)+14
=6x^2+12x-4+14
=6x^2+12x+10
f[g(-2)]=6 (-2)^2+12×(-2)+10
=12- 24+10
=-2
