Answer:
113 or 401: see below for explanation
Explanation:
x = 8
The way you wrote it with the " * " symbol, it means the multiplication of 6x and 2. This is what I did in the line below.
6x × 2 + 17 = 6 × 8 × 2 + 17 = 48 × 2 + 17 = 113
If by " * " you actually meant an exponent, such as 6x², then here is the calculation using 2 as an exponent. For exponent, we normally use ^, such as 6x^2 to mean 6x².
6x² + 17 = 6 × 8² + 17 = 6 × 64 + 17 = 384 + 17 = 401
