The answer is 21 which comes from 7 * 3.

Draw the four points in a complex plane. From the drawing you can see that the lenght is 4i - (-3i) = 4i + 3i = 7i, and the width is 1 - (-2) = 1 + 2 = 3.

So, the area is 7 * 3 = 21.

PLEASE HELP!!!!!!!!!!

Hi there!

<em><u>Another student asked this same question. Here is the link to the answer. I will still leave you the full answer down here just in case :</u></em>

I am not sure which "x" you are talking about, the one for the third angle or the one in the parentheses representing another angle.


If you are wondering what the value of "x" being the third angle is, the answer is 60° since this is an equilateral triangle and all the angles are equal to 60°.


But I am pretty sure that you are looking for the value of the "x" in the parentheses. To find its value, you need to create an equation and solve it by isolating "x". Since we know that all the angles are equal to 60°, your equation should look like this :


2x - 4 = 60


Add 4 on each side of the equation


2x = 64


Divide each side of the equation by 2


x = 32



There you go! I really hope this helped, if there's anything just let me know! :)

A statistics teacher started class one day by drawing the names of 10 students out of a hat and asked them to do as many pushups
HACTEHA [7]

Answer:  b. 8.56 to 21.44

Step-by-step explanation:

Let  \mu be the  mean number of pushups that can be done.

As per given , we have

Sample size : n= 10

Degree of freedom = n-1=9

Sample mean : \overline{x}=15

Sample standard deviation : s=9

Significance level : α=1-0.95=0.05

From t- distribution table ,

Critical two -tailed t-value for α=0.05 and df = 9 is

t_{\alpha/2, 9}=t_{0.025,9}=2.2622

Confidence interval for \mu is given by :-

\overline{x}\pm t*\dfrac{s}{\sqrt{n}}

=15\pm (2.2622)\dfrac{9}{\sqrt{10}}\\\\\approx 15\pm 6.44=(15-6.44,\ 15+6.44)\\\\=(8.56,\ 21.44)

Hence, the  95% confidence interval for the true mean number of pushups that can be done is 8.56 to 21.44.

How does a residential survey help buyers?
Gnoma [55]
<span>C) buyers are aware of the accurate measurements of the property. A residential survey is also known as a boundary survey and is used to determine the boundaries of a piece of property. It is generally required as part of the process of building new construction on a property to insure that the construction doesn't cross the property line and intrude on someone else's property. With this in mind, only option "C" reflects what a residential survey is.</span>
