Answer:
72 inches
Explanation: because if you divide 72 by 12 you would have 6 and that would be 6 feet
There are no numbers without decimals which multiply to 78 and add up to 17.
1/√6 - √11 + √5
LCM = √6
(1 - (√6)*(√11) + (√5)*(√6) ) / √6
(1 - √(6*11) + √(5*6) )/ √6
Rationalize the surd by multiplying top and bottom by √6
((1 - √(6*11) + √(5*6) )/ √6) * (√6/√6)
(√6 - √(6*6*11) + √(5*6*6)) / √6
(√6 - 6√(11) + 6√(5)) / 6
So answer is:
(√6 - 6√11 + 6√5) / 6
The answer of square root of -121 is 11
Well to simplify it we combine the x's: 4x+11, then to solve for x:
4x= -11
x= -11/4
