"Theorems 1 and 2 imply" vs. "Theorem 1 and Theorem 2 imply"

Question

To convey that $$\text{Theorem 1} \wedge \text{Theorem 2} \implies A$$ which style is better?

Theorems 1 and 2 imply $A$.

Theorem 1 and Theorem 2 imply $A$.

Which style manuals prefer which form?

(This question concerns the repetition of the word theorem, not the capitalization.)

Answer 1

Besides style, I think there's an issue of ambiguous interpretation:
  "Theorems 1 and 2 imply..." suggests to me that $\mbox{Thm}1\ \&\ \mbox{Thm}2\Rightarrow\mbox{Thm}3$.
But "Theorem 1 and Theorem 2 imply..." might more easily be interpreted to mean
  $\mbox{Thm}1\Rightarrow\mbox{Thm}3\ \ \&\ \ \mbox{Thm}2\Rightarrow\mbox{Thm}3$
