B is the answer to the question
Simplify √20 to 2√5
2 * 2√5 - 3√7 - 2√5 + 4√63
Simplify √63 to 3√7
2 * 2√5 - 3√7 - 2√5 + 4 * 3√7
Simplify 2 * 2√5 to 4√5
4√5 - 3√7 - 2√5 + 4 * 3√7
Simplify 4 * 3 √7 to 12√7
Collect like terms
(4√5 - 2√5) + (-3√7 + 12√7)
Simplify
2√5 + 9√7
Answer: B
Answer:
Raj will take 10 minutes
explanation:-
Raj types 20 words per minute
Saleem types 40 words per minute
I. e speed and time are inversly proportional.
therefore, Raj will take twice the time Saleem takes.
Raj takes 2 * 5 = 10 minutes
