Side BC is 4 meters long. Side CD is twice the length of the side BC. What is the length of side LM. Explain your reasoning.

Misha Larkins [42]

Answer:

LM = 18

Step-by-step explanation:

BC = 4

CD is twice that, so CD is 8

Now, remembering that the area of ABCD = 32 and JKLM = 72, divide 72 by 32.

You get 2.25. This is how much bigger JKLM is than ABCD.

Using that, multiply the length of CD (which is 8) by 2.25 to get the length of LM.

You'll get 18.

Hope this helps!

Use the table to answer the question.

Vesna [10]

Given:

The table of values of a linear relationship.

x y

-1 -1

0 1

1 3

2 5

To find:

The equation for the given table of values.

Solution:

If a linear function passes through the two points, then the equation of the linear relationship is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Consider any two point from the given table. Let the two points are (-1,-1) and (0,1). So, the equation of the linear relationship is

$y-(-1)=\dfrac{1-(-1)}{0-(-1)}(x-(-1))$

$y+1=\dfrac{1+1}{0+1}(x+1)$

$y+1=\dfrac{2}{1}(x+1)$

$y+1=2(x+1)$

Using distributive property, we get

$y+1=2(x)+2(1)$

$y+1=2x+2$

Subtracting 1 from both sides, we get

$y+1-1=2x+2-1$

$y=2x+1$

Therefore, the required equation is $y=2x+1$ . Hence, the correct option is D.
