-14x-7=15x-12

Add 14x to both sides

-7=29x-12

Add 12 to both sides

5=29x

Divide by 29 on both sides

x=5/29

So, x=5/29.

sqrt(145) = 12.0415945787922955

Rounded to thousandths is 12.042

45^17 = 12723679885609870147705078125

a^7 - 14 a^6 + 84 a^5 - 280 a^4 + 560 a^3 - 672 a^2 + 448 a - 128

The second term of that is -14a⁶

3sqrt(2)^2 = 6

If the dash is a minus in front of the 3, change the answer above to negative 6
