The product of 5 and a number x is 14 .

what is the value of x?

x=194

x=120

x=54

x=434

none of them.

 Product means multiplication, so the product of 5 and a number means 5 times a number which is 5x

 so if 5x = 14

x = 14/5 = 2.8

x = 2.8 which isn't a choice.

mr. graef told us it is 13 pints

step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
