Answer: 15 feet

Step-by-step explanation:

Given: Quadrilateral ABCD is similar to quadrilateral EFGH.

If the two shortest sides of quadrilateral EFGH are 6 feet long and 12 feet long.

Let x be the shortest side of quadrilateral ABCD .

The measurement of sides of  quadrilateral ABCD arranged in order :-

60 feet , 40 feet, 30 feet and x feet.

We know that the corresponding sides of two similar polygons are proportional.

⇒ The two shortest sides of quadrilateral ABCD is proportional to the two proportional sides of quadrilateral EFGH.

⇒\dfrac{6}{12}=\dfrac{x}{30}\\\\\Rightarrow\ x=\dfrac{30\times6}{12}=15

Hence, the length of the 4th sides of quadrilateral ABCD = 15 feet.

6x= 267

x=267/6= 44.5

2x= 44.5*2= 89

3x= 44.5*3= 133.5

largest integer = 133.5

Help..... me .......please..........ITS URGENT

Answer: 115, 2645

(x= 115, y= 2645)

Step-by-step explanation:

There are two methods to this, which is using the graph with each x and y value, or substituting in values.

I would suggest looking at the graph first and then substituting values so you know the equation is being satisfied by the ordered pair.

In this case, one way to check it could look like this (substituting y value):

y = 23x

2645 = 23x

x = 2645÷23

x = 115
