Step-by-step explanation: To simplify the expression 25/30 + 10/30, we first need to find a common denominator. The least common multiple of 30 and 30 is 30 itself, so we can multiply all the fractions by 30. This gives us:
(25/30)(30/30) + (10/30)(30/30) = 75/90 + 10/90
Next, we add the fractions:
75/90 + 10/90 = 85/90
Therefore, 25/30 + 10/30 = 85/90.

Answer:
Step-by-step explanation:
Consider the equation
The zeros of the equation can be the divisors of 18:
Check them:
So, x=-2 is zero. Now
Thus, x=3 is the second root (of multiplicity 2)
