Answer:
A and D
Step-by-step explanation:
Ok so first, if you slice parallel to the base, you can get a square.
If you slice parallel to a face, you get a triangle.
(m−5)(2m−2)
=(m+−5)(2m+−2)
=(m)(2m)+(m)(−2)+(−5)(2m)+(−5)(−2)
=2m2−2m−10m+10
=2m2−12m+10
-9=v/4
cross multiply
-9×4=v
-36=v
v=-36
f+6
f+6 =(f+6)
