Expanded=4x+12+6x+12
Simplified=10x+24
Answer:
10
Step-by-step explanation:
If we plug in any negative number as x, the result will always be greater than 4, which rules out answers A and B
lets try plugging in 4 as x to test answer C:
2(8-4)
2(4)= 8
8 is greater than 4, therefore C is wrong.
Lets try 10 as X (answer D):
2(8-10)
2(-2)
-4
We know that -4 is less than 4, therefore it makes the inequality true! :)
If (x+2) is a factor of 3x^2+14x+k, the equation must equal zero when x=-2 so:
3(-2)^2+14(-2)+k=0
12-28+k=0
-16+k=0
k=16
