Which represents all the values of x that make the rational expression undefined? x = –3 x = 7 x = –7 or x = 7 x = –3 or x = 3

The value of x would be -3.

Step-by-step explanation:

Consider the complete question is,

'Which represents all the values of x that make the rational expression undefined?'

Since, the rational expression is defined for all real values except those for which denominator is equal to zero,

If 3x + 9 = 0,

3x = -9

Hence the values of x that make the rational expression undefined would be -3.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
