Which of the following expressions represents "The product of 9 and a number, diminished by 7"?a)9n - 7

b)9n · 7

c)9(n + 7)

Answers

Answer:

a) 9n-7

Step-by-step explanation:

Let the unknown number be represented by placeholder n.

Then the product of 9 and the number is represented by 9*n or 9n.

This value diminished by 7 corresponds to 9n - 7.

So the expression representing the required overall construct mathematically is given by 9n-7

Option b, 9n * 7 represents the product of 9n and 7.

Option c, 9(n+7) represents the product of 9 and (n incremented by 7).
a)9n - 7

B show product of 9 and a number multiplied by a number
C shows the product of number plus 7 and 9
