4n-2n+4=-1+17

2n+4=-1+17

-1+17=16

2n+4=16

Move + 4 to the other side. Sign changes from +4 to -4

2n+4-4=16-4

2n=12

Divide by 2 for 2n and 12

2n/2=12/2

n=6

Check answer by using substitution method

4(6)-2(6)+4=16

24-12+4=16

12+4=16

16=16

Answer : n=6

__mm x 9mm x 12mm=756mm
Anna [14]
7 mm x 9mm x 12mm = 756mm


To get this answer you have to multiply 9 and 12 which would be 108. Then you have to divide 108 on both sides to get mm by itself. 756 divided by 108 is 7 which is the answer!

Dahasolnce [82]

Answer:

\frac{2 \sqrt{7}  + \sqrt{3}}{3 \sqrt{7} -  \sqrt{3}  }  =  \frac{2 \sqrt{7}  + \sqrt{3}}{3 \sqrt{7}  -  \sqrt{3} } . \frac{3 \sqrt{7} +  \sqrt{3}  }{3 \sqrt{7} +  \sqrt{3}  }  \\  \\  =  \frac{(2 \sqrt{7} + 3)(3 \sqrt{7}  +  \sqrt{3})  }{(3 \sqrt{7}  - 3)(3 \sqrt{7} +  \sqrt{3} ) }  \\  \\  =  \frac{(42 + 2 \sqrt{21} + 9 \sqrt{21}   + 3 \sqrt{21} )}{63 - 3}  \\  \\  =  \frac{42 +  2\sqrt{21}  + 9 \sqrt{21} + 3 \sqrt{21}  }{60}
