Question

the expression a(4.15) is equal to \square for a = 7. (type a whole number or a decimal.)

Explanation:

Step1: Substitute a with 7

We know that \( a = 7 \), so we substitute \( a \) in the expression \( a(4.15) \) with 7, getting \( 7\times4.15 \).

Step2: Calculate the product

Calculate \( 7\times4.15 \). \( 7\times4 = 28 \) and \( 7\times0.15 = 1.05 \), then add them together: \( 28 + 1.05 = 29.05 \).

Answer:

29.05
