(4/(x+4-2))/x+1
4/(x+2)=x/4+1/2
(x/4+1/2)/x+1
x=-2/5
Answer:
Step-by-step explanation:
Break down the figure into two shapes.
SHAPE A: The larger one. We can infer the size of the bottom is 6 cm because it's the same size as it's top counterpart. Same goes for the left side, which will have a measure of 7 cm.
SHAPE B: The smaller one. We're going to use the same method as we did with the first one, and infer the lengths of the other sides using the existing ones.
To calculate area, it's length times width.
SHAPE A: Its two side measures are 6 and 7, which equates to 42 cm^2.
SHAPE B: Its two side measures are 2 and 3, which equates to 6 cm^2.
If you add the two, the total area is 44 cm^2.
2500x0.80=2000 so i think it would be 2000 in 8 years
or if youre adding the 2000 to the already existing 2500 then it would be 4500.
x=1 f = 10(5.5)(1) = 55
x=2, f = 10(5.5)(2) = 110
110-55 = 55
2-1 =1
55/1 = 55
average rate of change = 55
K, you have 2 minutes, one minute for one kilometer.
If you're in 60km/h, you're on 1km/m, so, if you cover 1 km in one minute, you need to stay in that speed to get to the train station.
