Answer:
126
Step-by-step explanation:
Row 1: 30+0*4
Row 2: 30+1*4
Row 3: 30+2*4
...
The list goes on. Do you see a pattern here? If we call the row number as r, the formula is 30+(r-1)*4. In the 25th row, the r is 25. So in the formula, it is 30+(25-1)*4=30+24*4=126.
I hope that helped.

Answer:
Step-by-step explanation:
Factor all the factors making up the square root.
108: 2*2*3*3*3
a^7: a*a*a*a*a*a*a
b^5:b * b * b * b * b
The rule for taking a square root of this is
For every pair, you get to take one number outside the root sign and throw the other one away.
2*3*a * a * a* b * b√(3*a * b)
6a^3b^2 * √(3*a*b)
<span>2/3 (x-7)= -2
x - 7 = -2 * 3/2
x - 7 = -3
x = -3 + 7
x = 4</span>
