A rational expression is a ratio of two polynomials. To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same.
4+3 = 7
This is the amount of dollars spent each day
25/7 = 3 4/7

Answer:
14
Step-by-step explanation:
61.68 = 62
48.225= 48
62-48= 14
No it is not because 12 kg is equal to 12,000,000mg, which is greater than 70 mg.
Set each of the binomials equal to zero and solve for x. The two values will be the zeros of the equation:
(x-4) = 0 (x+11) = 0
x-4 = 0 x + 11 = 0
x = 4 x = -11
The zeros of the equation are -11 and 4
