which value is equivalent to $\frac{x + 4}{4 + x}$?\n-4\n-1\n1\n4

Answer:

C. 1

Explanation:

Step1: Use the commutative property

By the commutative property of addition, $x + 4=4 + x$.

Step2: Simplify the fraction

So, $\frac{x + 4}{4 + x}=\frac{4 + x}{4 + x}=1$ (assuming $x\neq - 4$, as when $x=-4$, the fraction is undefined. But in terms of the non - zero values of the denominator, the simplified form is 1).
