Answer:
B
Step-by-step explanation:
-1/2
Answer:
<h2>The answer would be negative five over one or -5/1 </h2>
The letter that has no right angles is N
Das is difference of 2 perfect squares
remember
a^2-b^2=(a-b)(a+b)
so
25x^4=(5x^2)^2
16y^2=(4y^2)
(5x^2)^2-(4y)^2=(5x^2-4y)(5x+4y)
cannot be factored further
