To eliminate the i in the denominator, you multiply it by (6+5i), because (a+b)(a-b)=a²-b², we need i² to eliminate i. Recall that i²=-1
-1(6+5i)/(6-5i)(6+5i)=(-6-5i)/[6²-(5i)²]=(-6-5i)/(36-25i²)=(-6-5i)/61
your choices are all correct. You need to check the 7th answer as well.
You only wrote one option, but luckily, those two fractions ARE equivalent!
We know that because if you multiply the denominator AND numerator by 4, you get 16/20.
Answer: w=-6/14
Step-by-step explanation:
First you are going to put one equation on top of the other and subtract. Then you will use your new equation to combing like terms then divide your end result by your w value and make an improper fraction.
Numerical expressions use numbers and algebraic expressions use variables.
Answer:
44 inches
Step-by-step explanation:
A regular sized printer paper is 8.5 x 11 inches. Since the long side is 11 inches, and there are 4 papers 11 x 4 us 44.
