Answer:
C
Step-by-step explanation:
We see that we can factor out 2x from the equation! So our equation becomes 2x(x-2) = 0.
Since the only way for things to multiply to equal to zero is if at least one of the numbers is 0.
So if x-2 is the 0, then x = 2.
If 2x is the 0, then x = 0.
So our answer is C. 0,2
Answer:
124 million in 2007
Step-by-step explanation:
This is a proportion match question, we consider 121-116 to represent a 9 year change = 5 rate of change per 9 years. We need to find one year so we divide 5/9=0.55 per year growth. =2002- 2007= 0.55 million x 5 = 2.8million growth add 121 million = 121 =123.8 in 2007 = 124 million to nearest m.
Answer:

30
Step-by-step explanation:
Do 5 times ten.
5 times -6
Gives you 20
Then do 6 times 4, 6 times 10, to get the final answer of 30.
Answer:
x=-1,-2
Step-by-step explanation:
Multiply the given equation with (x+1) on both sides. We'll get,
x+2/x=-3
or,x^2+2=-3x
or,x^2+3x+2=0
or,x^2+2x+x+2=0
or,x(x+2)+1(x+2)=0
or,(x+2)(x+1)=0
or,x=-2,-1
Answer:
The value of Mary's investment after two years = £12362.7
Step-by-step explanation:P = Principal / initial amountR = rate of interest per cent per yearT = number of yearsA = final amount at the end of T yearsThen:A = P*(1 + R/100)^2In our example:P = £12000R = 1.5 per cent per yearT = 2 yearsThus:A = 12000*(1 + 1.5/100)^2 = 12000*(1 + 0.015)^2 = 12000*(1.015)^2 = 12000*(1.030225) = 12362.7Value of investment after two years = £12362.7
