Solve the equation 1/30 + 1/45 = 1/x
where x is the required time
multiply thru by 90x:-
3x + 2x = 90
x = 90 / 5 = 18
answer 18 minutes

Given:
divided by 
To find:
The remainder.
Solution:
divided by 
<u>Remainder theorem:</u>
<em>If a polynomial p(x) is divide by x - a, then the remainder is p(a).</em>

Subtract 2 from both sides, we get

substitute x = -2 in p(x).




The remainder is 55.
