Well this is a hard question to answer, but this is how i would put it.
You would take a number (lets use 15) and the second number (lets use 5) would determine how many times it would go into 15. In other words, 5 time x would equal 15 (5x=15). 5, being a factor of 15, would evenly fit into 15 three times.
I assume you mean divide using the conjugate to rationalize the denominator and express the result in standard rectangular form.

120 * 45 % = 120 *0,45 = 54 £
120 -54 = 66 £
Answer:
1/4 N + 15
the coefficient is "n" it is a letter variable associated with a term
Step-by-step explanation:
Answer:
Choice 'D' (10x + 9) (10x-9) is the correct answer
Step-by-step explanation:
100x^2 - 81
This is a difference of squares...
therefore = (10x + 9) (10x - 9)
