Answer:
no solution
Step-by-step explanation:
x²-4 is (x+2)(x-2), which is your least common multiplier
So first, eliminate the denominators by multiplying all terms by (x+2)(x-2)
(x+2)(x-2)/(x-2) + (6x)(x+2)(x-2)/(x+2)(x-2) = 3(x+2)(x-2)/(x+2)
Then simplify
(x+2) + (6x) = 3(x-2)
combine the variables, and expand the right side of the equation
7x + 2 = 3x - 6
Subtract 2 from both sides
7x = 3x - 8
Substract 3x from both sides
4x = -8
Divide both sides by 4
x = -2
Although x = -2, the final answer is undefined.
Because if you plug x = -2 back into the equation, you would get...
for example, 3/(x+2) will become 3/(-2+2), which is 1/0
it is not possible to divide by 0
anything divided by 0 is undefined, therefore this equation has no solution.

Two airplanes leave the airport at the same time. One plane is flying 700mph at a bearing of N46°W and the other plane is flying 895mph at a bearing of
N43° E. After 3 hours, how far are the planes from one another?
Answers
9514 1404 393
Answer:
3380 miles
Step-by-step explanation:
The distance separating the planes can be found using the law of cosines. One plane has gone 3×700 = 2100 miles; the other has gone 3×895 = 2685 miles. The angle between their flight paths is 46°+43° = 89°. Then the separation (s) is ...
s² = 2100² +2685² -2(2100)(2685)cos(89°) = 11,619,225 -11,277,000×0.01745
s² ≈ 11,422,414.21
s ≈ √11,422,414.21 ≈ 3379.7
The planes are separated by about 3380 miles after 3 hours.

Q.10) John makes clay cups. He makes 18 cups each hour. He makes cups

all the cups John makes in a week?*

Answers
Correct question is;
John makes clay cups. He makes 18 cups each hour.
He makes cups for 6½ hours each day, on 5 days of the week.
The cups are packed in boxes.
4 cups are packed into each box.
How many boxes are needed for
all the cups John makes in a week?
585
146.25
146
147
Answer:
147
Step-by-step explanation:
Since he makes 18 cups each hour and we are told that he makes it for 6½ hours each day.
Thus, amount of cups made per day = 18 × 6½ = 18 × 13/2 = 117 cups
She works 5 days a week.
This means;
Cups produced for the week = 117 × 5 = 585 cups
We are told that the cups are to be packed in boxes. Also that 4 cups are packed into each box.
Thus, number of boxes = 585/4 = 146.25 boxes
Since, we can't have a decimal as number of boxes, to fit everything we approximately need 147 boxes

Simply each expression my factoring 5m-15
Answers
Answer:
5(m-3)
Step-by-step explanation:
The first step in factoring is to bring out the greatest common factor. In this case, the GCF between 5m and -15 is 5.
To find out out the expression inside the parenthesis, divide the current expression by the GCF,
(5m-15)/5
m-3
Multiply that by the GCF.
5(m-3)
