d + 8
8 more than twice a number d
2d+8

8z + 5
If you are seeking d more than 7, you'll need to add d to 7. We find that d + 7 is d more than 7. In this case, d is a variable, but the math is direct and correct.
3d-8. Another way to write this would be (3*d)-8.
A heptahedron, octahedron, nonahedron, etc. All -hedrons with prefices refering to 8 or more.
a is 6 less than d.
8 more than -5 = 3
8 is more than 5.
8 is more than 2.
