Answer: Choice A) 15 feet

=====================================

x = length of fourth side in quadrilateral ABCD

Have a look at the attached image I've posted. I made a chart that lines up the side lengths from largest to smallest. Note how the first two items in the bottom row are blank. We don't know these values and we don't need to find out in order to find x.

Based on the last two columns of that table, we can form the proportion below, which is then used to isolate x.

30/12 = x/6

30*6 = 12*x ... cross multiply

180 = 12*x

12*x = 180

x = 180/12 ... divide both sides by 12

x = 15

Sati [7]

Answer:

The volume in liters is 2.041165665 liter.

Step-by-step explanation:

Given : Clare wants to mail a package that weighs $4\frac{1}{2}$ pounds.

To find : What could be its volume in liters ?

Solution :

We know that,

Pound (lb) is a unit of Weight used in Standard system.

Liter (l) is a unit of Volume used in Metric system.

To convert 1 pound into liter is

1 pound (lb) = 0.45359237 liter (l)

$4\frac{1}{2}$ pounds in simpler fraction is $\frac{9}{2}$

Converting into liter,

$\frac{9}{2}$ pound (lb)= $\frac{9}{2}\times 0.45359237$ liter (l)

$\frac{9}{2}$ pound (lb) = 2.041165665 liter (l).

Therefore, the volume in liters is 2.041165665 liter.

Solve 11b^2-9=-68 using the square root method

Vladimir79 [104]

Answer:

b=i* $\sqrt{\frac{59}{11} }$ or -i* $\sqrt{\frac{59}{11} }$

Step-by-step explanation:

11b^2-9=-68

11b^2=-59

b^2=-59/11

b=i* $\sqrt{\frac{59}{11} }$ or -i* $\sqrt{\frac{59}{11} }$

"i" in this case is an imaginary number, equal to $\sqrt{-1\\}$

What is 2xy-3yz+5+2yz-xy

melomori [17]

To simplify this expression, we are going to combine like terms.

First, we can see that we have two terms with the variables $xy$ being multiplied together, $2xy$ and $-xy$ . Together, these add to $xy$ , so our expression is now:
