Final answer:
The value of the expression (x)(z + y) with x = 5, y = 6, and z = 3 is 45, which is option B.
Step-by-step explanation:
To find the value of the expression (x)(z + y) when x = 5, y = 6, and z = 3, we must first evaluate the sum inside the parenthesis (z + y). So, we calculate 3 + 6, which equals 9. Next, we multiply this sum by the value of x, which is 5. Therefore, the calculation becomes 5 × 9, which results in 45. The value of the expression (x)(z + y) given the provided values of x, y, and z is 45, which corresponds to option B.
