Answer:
The answer should be 43
Explanation:
Let's assign the variable "x" to represent the number. The expression can be written as:
x^2 - 6
Since we don't have a specific value for x, we'll substitute it with c = 7:
7^2 - 6
Simplifying further:
49 - 6
Which equals:
43
Therefore, the value of the expression "a number squared decreased by six" when c = 7 is 43.
