Question

evaluate the expression when a = 1.

a·-7

Explanation:

Step1: Substitute \( a = 1 \) into the expression \( a \cdot -7 \)

We replace \( a \) with \( 1 \) in the expression \( a \cdot -7 \), so we get \( 1 \cdot -7 \).

Step2: Calculate the product

The product of \( 1 \) and \( -7 \) is \( -7 \) because any number multiplied by \( 1 \) is the number itself, and \( 1 \times -7=-7 \).

Answer:

\(-7\)
