Answer:
x = 2 x = -6
Step-by-step explanation:
2 (x+2) ^2-4=28
Add 4 to each side
2 (x+2) ^2-4+4=28+4
2 (x+2) ^2= 32
Divide by 2
2/2 (x+2) ^2=32/2
(x+2)^2 = 16
Take the square root of each side
sqrt((x+2)^2) =±sqrt( 16)
x+2 = ±4
Subtract 2 from each side
x+2-2 = -2±4
x = -2±4
x = -2+4 and x = -2-4
x = 2 x = -6
The median is 1 because that is the number in the middle

Step-by-step explanation:
Discussion
The first thing you have to do is convert km to miles
Formula
1 mile = 1.6 km
x mile = 40000 km Cross Multiply
Solution
1.6*x = 1 * 40000 Divide by 1.6
x = 40000/1.6
x = 25000 miles
Answer Part 1
The distance covered is 25000 miles
Discussion Part 2
That's the distance covered in a day. Now we need to convert that to speed. The time (in hours) for 1 day is 24 hours.
Givens
d = 25000 miles
t = 24 hours
s = ?
Solution
s = d/t
s = 25000 / 24
s = <u>1041.66 </u> miles per hour
Answer: 1041.66 is what is to be entered as your answer
Answer: x = -11
Step-By-Step:
We can start by combining like terms on the left side.
-20 - x = 4x - (3x - 2)
Now we need to distribute the negative on the right side.
-20 - x = 4x - 3x + 2
Now combine like terms on the right.
-20 - x = x + 2
Now add 20 to the other side
- x = x + 22
Subtract x from the left side.
-2x = 22
Now divide by -2.
x = -11
