Question

Optics/Lens problem. Is the image real or virtual?
A converging lens of focal length f1 = +22 .5cm is placed at a distance d = 60 .0cmtotheleft of a diverging lens of focal length f2 = −30.0cm. An object is placed on the common optical axis of the two lenses with its base 45.0cm to the left of the converging lens. (The thin-lens approximation may be assumed to hold.)

Is the final image real or virtual? And is it inverted or ereet?
