Answer:

Step-by-step explanation:
To add two fractions we need a common denominator. Just by looking at the two, there are no common factors. This means the denominator would be the product of the two: 4x(x-8). In order to obtain this, we multiply the first fraction by (x-8)/(x-8) - 1, and the second by 4x/4x - 1:

We can use the distributive property to simplify:

The sum of the two is:

Answer:
a)negitive b)positive
Step-by-step explanation:
to the left of zero on a number line is negitive numbers and to the right is positive
This is a ratio problem:
26/18 = 39/x
to solve for x cross multiply: 18 * 39 = 702 and then divide by 26
702 / 26 = 27
x = 27
