R/ r+ 15 = 3/8
Cross multiply: top of one side multiplied by bottom of other side:
R x 8 = 3 x r+ 15
Simplify:
8r = 3r + 45
Subtract 3r from both sides:
5r = 45
Divide both sides by 5:
R = 9
How you would solve it is by 8 multiplied by 4.
The formula B*H
So the answer is 32cm squared.
Answer: 45
Step-by-step explanation:
The sides are 2x,3x,4x
Add them up and you have 9x=45
Answer:
Step-by-step explanation:
A complex number is a number which has some real part and some imaginary part.
Standard form of a complex number is represented as
Where 
is the real part,
and 
is the imaginary part.
And 
Given complex number:
Hence, the standard form is .
