Answer:

1. 5/4

2. 7

Step-by-step explanation:

1) Lets call the width as w

Therefore length would be:

w+4

To find the perimeter you use the formula:

2 (l+w)

Now substitute our values into this formula:

2 (w+4+w)

2( 2w+4)

4w+8

Now make this equal to 13:

4w +8 = 13

4w = 5

w = 5/4

2. In this question we will call length l

Therefore width would be:

l-5

Now we will do the steps we did above:

2 (l+l-5)

2 (2l-5)

4l -10

4l - 10 = 18

4l = 28

l = 7

NEED ANSWER ASAP PLEASE WILL GIVE BRAINLIEST An integer n is divided by 2 and the quotient is an even integer. What does this te

Nesterboy [21]

Answer:

$n$ is a multiple of 4

Step-by-step explanation:

Let's think about this.

Even numbers are basically numbers that, when divided by 2, get us an integer.

This means that $n$ must be an even integer.

<em>However,</em>

Every other even number, when divided by 2, gets you an odd integer.

This means that every second even number, $n \div 2$ gets us an even number.

This also means that every time $n \div 2$ is an even number, n will be a multiple of 4 (as $2\cdot 2 = 4$ ).

Test this out with any even number that's a multiple of 4 (all multiples of 4 are even numbers)

Hope this helped!

The cost of manufacturing x refrigerators is given by the function f(x)=2x^2+6000. If the cost doubles fr the year 2011 owing to

Alecsey [184]

Answer: Vertical Stretch

Step-by-step explanation:

Given: The cost of manufacturing x refrigerators is given by the function : $f(x)=2x^2+6000$

If the cost doubles fr the year 2011 owing to higher raw material prices, then we multiply the given function by 2, then we get a new function :

$g(x)=2(2x^2+6000)=4x^2+12000$ which represents a vertical stretch in the graph.

∵ 2 is a positive constant greater than 1 which is multiplied to the parent function f(x). So by the definition of vertical stretch the parent function will be vertically stretched .

Lol please help meeee

jeyben [28]

Answer:

4 . The answer is no .

5 . x=1

6. unlimited answers

7. There's no answer to this question .

Step-by-step explanation:

___________________

4. solution :

-20(2-4) = 2((5×-4) -4) =

-40 = -48 × impossible

___________________

5. solution :

-3+4x+12x+24 = 28x +12-3

-3+24-12+3=28x-12x-4x

27-15=12 = 2x - 16x =12x

12 = 12x

x =1

__________________

6. solution :

24-3x+9-6 = -8x+20+5x+7

8x-5x-3x = -24-9+6+20+7

0=0

x can be every number you think because they are always equal to each other .

examination :

if you consider x as 1 :

24-3+9-6=-8+20+5+7

24=24

or if you consider x as 2 :

24-6+9-6 = -16+20+10+7

21 = 21

__________________

7 . solution :

3(x-2) = 3x+4

3x-6 = 3x+4

3x-3x = 10

0 = 10

if you consider x as 1 :

3-6 = 3+4

-3 = 7 × impossible .

Write the number in witch the digit 2 is one tenth the value of the digit 2 in 8.524.

spin [16.1K]

Well the 2 in 8.524 would be 0.02 or 2 hundredths. Here's my explanation, the 8 is the whole number because it's before the decimal point, the 5 is the tenth or 0.5 and as you go further the number gets smaller so after the 5 is the 2 and that would be 2 hundredths or 0.02. So basically it's like going from tens, to hundreds, to thousands but only going in reverse order.
