Yes, because 3×(4x)= 12x (3 times 4 is 12. add the "x" and you have 12x) and 3×8=24 . If you put the two together, you get 12x+24 as the expression. ^_^
Wow that looks really easy.
This is tricky
lets try substituting y = √)6x - 9)
√(6 - y) + √(6x + y) = √6
squaring both sides:-
6 - y + 6 + y - 2√(6 - y)(6 + y) = 6
12 - 2√(6 - y)(6 + y) = 6
√(6 - y)(6 + y) = (6-12) / -2 = 3
Squaring both sides:-
(6 - y)(6 + y) = 9
36 - y^2 = 9
y^2 = 27
y = +/-√27
√(6x - 9) = +/- 27
6x - 9 = 729
x = 738/6 = 123
This cannot be a solution because we would have a negative value for the
second square root
I would say that no solution exist.
75 minus 31 would be your answer of n
The answer would be D.= $140,493
