Answer: B
Explanation:
Given, f(x) = 3 • 2x
So , f(-2)=> x= -2
f(-2)= 3 • 2(-2)
f(-2)= 3 •(-4)
f(-2)= -12
Answer:
40.38 Is the answer :)
Step-by-step explanation:
The value of x is -9 and 3.Option D.
Step-by-step explanation:
Given,
To find the value of x.
We will apply middle term factor formula.
The given equation can be written as,
or, 
+(9-3)x-27 = 0
or, x²+9x-3x-27= 0
or, x(x+9)-3(x+9)=0
or, (x+9)(x-3) = 0
So, x = -9 and x = 3
Hence,
The correct option is Option D.
