The sides of a quadrilateral are 3, 4, 5, and 6. Find the length of the shortest side of a similar quadrilateral whose area is 9 times as great.

Answers

Answer:

9 units.

Step-by-step explanation:

Let us assume that length of smaller side is x.

We have been given that the sides of a quadrilateral are 3, 4, 5, and 6. We are asked to find the length of the shortest side of a similar quadrilateral whose area is 9 times as great.

We know that sides of similar figures are proportional. When the proportion of similar sides of two similar figures is $(m)/(n)$ , then the proportion of their area is $(m^2)/(n^2)$ .

We can see that length of smaller side of 1st quadrilateral is 3 units, so we can set a proportion as:

$(x^2)/(3^2)=(9)/(1)$

$(x^2)/(9)=(9)/(1)$

$x^2=9\cdot 9$

$x^2=81$

Take positive square root as length cannot be negative:

$√(x^2)=√(81)$

$x=9$

Therefore, the length of the shortest side of the similar quadrilateral would be 9 units.

the answer is 9

Solving systems of elimination 1) x-y=11
2x+y=19

2) 4x+8y=20
-4x+2y=-30

4) -6x+5y=1
6x+4y=-10
what are the answer to these three questions

Answers

To answer by systems of elimination, you add equations together to eliminate variables if they have the same amount of negative variables in one as the positive variables in another.
For example, in number one.

x - y = 11
2x + y = 19

Both equations contain a variable expressed in the same numbers of negative and positive in each of them, one positive y and negative y. This lets us add the equations together.
x + 2x = 3x
11 + 19 = 30
3x = 30
x = 10

Now that we know that x = 10, we can plug it into the first equation, x - y = 11 to find y.

x - y = 11
10 - y = 11
y = -1

For the second one,

4x + 8y = 20
-4x + 2y = 30

Negate the x's since there is the same and opposite amount, while adding the rest of the equations together.

8y + 2y = 10y
20 + 30 = 50
10y = 50
y = 5

Plug it into the initial equation to find x

4x + 8(5) = 20
4x + 40 = 20

Subtract 40 from both sides

4x = -20
x = -5

For the third equation,

-6x + 5y = 1
6x +4y = -10

Negate the x's, add the rest together

5y + 4y = 9y
1 - 10 = -9
9y = -9
y = -1

Plug it into the first equation to find x

-6x + 5y = 1
-6x + 5(-1) = 1
-6x - 5 = 1

Add five to both sides

-6x = 6
Divide both sides by negative 6
x = -1

When the problems do not have the same value of opposite versions of current numbers, for example:

3x + 4y = 6
-6x +g = 6

You can multiply an entire equation to get similar numbers of a variable.
For example, you can multiply the first equation entirely by 2 to get the same number of positive x's to the negative x's in the second one, changing it to 6x x 8y = 12.

Hope I helped.

How do I round these numbers?

Answers

Do your sum which is $329.69 subtract $59.63 then if the unit is 4 or less round your answer to the nearest ten eg, 103 would be rounded to 100. If the unit is 5 and above you would round your answer up eg, 437 would be rounded to 440.
