N-2=10n+4 over 2 what is the value of n
Snowcat [4.5K]

Consider the given equation:

n-2 = \frac{10n+4}{2}

Cross multiplying in the given equation, we get

(n-2) \times 2 = 10n+4

Applying distributive property which states a(b+c) = ab+ac, we get

(n \times 2) - (2 \times 2) = 10n+4

2n -4 = 10n+4

Adding '4' on both the sides, we get

2n-4+4 = 10n+4+4

2n = 10n+8

Subtracting '10n' from both the sides of the equation, we get

2n-10n = 10n+8-10n

-8n = 8

Dividing by '-8' in both the sides of the equation, we get

n= -1

Therefore, the value of 'n' is -1.

3 numbers are in arithmetic progression their sum is15 and their product is 80 determine the 3 numbers
Mashcka [7]

Answer:

2, 5, 8

Step-by-step explanation:

For starters, let us assume that the numbers are x-d, x, and x+d.

Where d is the common difference between terms.

This mean that we can say, from the question

x-d + x + x+d = 15

3x = 15,

x = 5,

This means that the terms are 5, 5-d and 5+d.

On the other hand,

(5-d) * 5 * (5+d) = 80

(5-d) * (5+d) = 80/5

(5-d) * (5+d) = 16

25 - d² = 16

d² = 9

d = + or - 3.

Finally, the three numbers will be 2, 5, and 8. On the flipside, their sum and product are 15 and 80.

Plzzz help<br> What is the distance between P(-3, -2) and Q(5, -2)?
Yuri [45]
Well first, you have to know the distance formula. You plug the coordinates into it and you get the answer.

\sqrt(-2 + 3) ^{2} + (-2 - 5) ^{2}

√1² + -7² = d

d = 7.1

Can I get help plz ?!? Mark BRAINLIEST?
maw [93]

Answer:

2

Step-by-step explanation:

Perimeter of a rectangle = 2(length + breadth)

=> 2{2x + (x + 4)) = 20

=> (2x + x + 4) = 20/2 = 10

=> 3x + 4 = 10

=> 3x = 10 - 4 = 6

=> x = 6/3 = 2

Here, according to the diagram

Length = 2x = 2(2) = 4

Breadth = x + 4 = 2+4 = 6

But breadth should always be lesser than the length. From this, it can be concluded that the actual breadth is 2x and actual length is x + 4, for perimeter to be 20.
