?

\newline

Choose

1

answer:

\newline

(A) Positive

\newline

(B) Negative

\newline

(C) Neither positive nor negative-the sum is zero.

Given Expression: We are given the expression $45 + (-38)$ and need to determine its sign. $\newline$ To find the sign of the sum, we simply perform the addition of the two numbers. $\newline$ $45 + (-38) = 45 - 38 = 7$
Determine Sign: Since $7$ is a positive number, the sign of the sum is positive.
Sign of the Sum: Now we can choose the correct answer from the given options: $\newline$ (A) Positive $\newline$ (B) Negative $\newline$ (C) Neither positive nor negative-the sum is zero. $\newline$ Since the sum is $7$ , which is a positive number, the correct answer is (A) Positive.
