Wrong those are considered complex numbers. pure imaginary numbers have ,0 for a and are thus in the form. 3i, -2i, 17i. etc

Answer:

<h2>False.</h2>

Step-by-step explanation:

<em>A pure imaginary number is a complex number that doesn't have a real part.</em>

So, if a is a real number, and it doesn't specify that a is only equal to zero, then the expression a+bi is not a pure imaginary number, it's only a complex number. Examples of imaginary numbers are 2i;3i;4i;....bi where b\inR

In this case, a\in R, that is, <em>a </em>can be 0, \±1, \±2, \±3, ...

<em>Therefore the statement is </em><em>false</em><em>, because a can take any real value.</em>

3 people work full time together on a project, but their total time on the project is to be equivalent to only 1 person working
NikAS [45]
Let x = the amount of time that the third person needs to work on the job to add up to one

1 = 1/2 + 1/3 + x

1 - 1/2 - 1/3 = x

To subtract the fractions we need to put them all over a common denominator. Let's use 3*2 = 6 as the denominator; so 1 = 6/6, 1/2 = 3/6, 1/3 = 2/6:

6/6 - 3/6 - 2/6 = x

1/6 = x

The third person must work 1/6 time on the project.

What is the area of the yellow square?The area of the green square is 9 ft2. The area of the red square is 16 ft2.
joja [24]
Well abnormal square would have four equal sides therefore for the firemen square since it's 9 ft^2 then u square root it and u get 3 that means each side in that green square is 3 now for the red one with 16ft^2 it would be the same consept u would square root 16 which u would get 4 now the two legs are 3 and four now u are missing the hypotenuse at c thus u use pythogerom theorom I don't know how to spell it so don't complain! You would do 3^2+4^2=c^2 which would result to 9+16=c^2. From there u would add and you would get 25 =c^2 and the reverse property of square would be square root it's that radical symbol if u remember so radical 25=5. We are still not finished we have to find the area and since we are working with normal squares where each sides ar eewual then u do 5*5 u get 25!
Now don't forget to write ft2 because then u will get it wrong
And don't be a lazy bum and try rechecking my work because I did it all in my head ok it's 12 o'clock a.m.
