Answer:
x<-16
Step-by-step explanation:
1/4x+6<2
1/4x<2-6
1/4x<-4
x<-4/(1/4)
x<-4(4/1)
x<-16/1
x<-16
Answer:
- no real solutions
- 2 complex solutions
Step-by-step explanation:
The equation can be rearranged to vertex form:
x^2 -4x = -5 . . . . . . . . . subtract 4x
x^2 -4x +4 = -5 +4 . . . . add 4
(x -2)^2 = -1 . . . . . . . . . show the left side as a square
x -2 = ±√-1 = ±i . . . . . . take the square root; the right side is imaginary
x = 2 ± i . . . . . . . . . . . . . add 2. These are the complex solutions.

<em>Comment on the question</em>
Every 2nd degree polynomial equation has two solutions. They may be real, complex, or (real and) identical. That is, there may be 0, 1, or 2 real solutions. This equation has 0 real solutions, because they are both complex.
The answer is D.
You cannot factorise it as there are two different terms being squared with the middle term containing both. Also, if you expand any of the brackets in the questions you will not get the original equation so non of them are right so it has to be D. :)
Answer:
2 candies were left.
Step-by-step explanation:
Number of bags of candies = 4 bags
Number of candies in each bag = 18 candies
Total number of candies = 
Ms. Rogers put an equal number of these candies into each of 7 gift boxes.
Divide 72 by 7
72 = 7(10) + 2
Here, remainder is 2.
So,
2 candies were left.
Answer: X= 4
Step-by-step explanation:
24+0.44x=19+1.69x exp equation like:
24+44x/100=19+169x/100
Multiply left and right side of equation with 100
2400+44x=1900+169x
2400-1900=169x-44x
500=125x
x=500/125
x=4
