Step-by-step explanation:

Hey there!!

According to the question,

One number is 7.

Let another no. be x.

So, the condition is 6(x+7)= 30

Now,

6(x+7) = 30

6x +42 = 30

6x = 30-42

x =  \frac{ - 12}{6}

Therefore the no. is -2.

Check,

6(-2+7)= -12 + 42 = 30 { they gets subtracted but sign remains (+) only }.

7- square root of 3i
r-ruslan [8.4K]

Step-by-step explanation:

Any complex number is of the form: a + bi where a is real part and B is imaginary part.

Therefore, in given complex number: 7- \sqrt {3}i

7 is real part.

\sqrt {3} is imaginary part.

Hence, first two options are correct.

Last two options are incorrect because of the following reasons:

- \sqrt {3} is coefficient of i & not 7- \sqrt {3}

Given number is a difference of a real number and imaginary number & not a sum of a real number and imaginary number.
