Multiply the bracket by 5
10x+25= 4x-7
10x-4x+25= 4x-4x-7
6x+25= -7
6x+25-25= -7-25
6x= -32
Divide by 6 for 6x and -32
6x/6= -32/6
x= -32/6
divide by 2 for -32/6
x= -16/3
Answer is -16/3 ( improper fraction) or -5 1/3 ( mixed number)
I believe the answer is the 3rd option Thermal conductivity. Hope this helps.

! Means starting from that number multiply by every number down to 1.
5!= 5•4•3•2•1 = 20•6=120
2!= 2•1=2
120+2=122 :)
The only factors that equal 62 are
62 • 1 = 62
and
31 • 2 = 62.
Hope this helps!
