4d + 12 = 4(d + 3)
Basically, you just need to determine what 4d and 12 have in common. In this case, they both divide evenly by 4. Therefore 4 (d + 3) = 4d + 12 according to the distributive property.
Step-by-step explanation:
Any complex number is of the form:
where a is real part and B is imaginary part.
Therefore, in given complex number:
7 is real part.
is imaginary part.
Hence, first two options are correct.
Last two options are incorrect because of the following reasons:
is coefficient of
& not
Given number is a difference of a real number and imaginary number & not a sum of a real number and imaginary number.
The value of x is 21√2/2
The correct option is (A)
<h3>What is Trigonometry?</h3>
Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
In triangle having angle 60.
sin 60 = P/ 7√3
√3/2= P/7√3
2P= 21
P= 21/2
Now again
cos 45= 21/2/x
1/√2 = 10.5/x
x= 21√2/2
