What is the sum? 3/x+4/x2 a. 3x+4/x3 b. 7/x c. 3x+4/x2 d. 7/x+x2

The correct answer is =(3x+4)/x²

Which is the third option

Step-by-step explanation:

This problem bothers on how well we can perform computations and manipulate our fractional Algebra

Given the expression 3/x+4/x²

In other to perform addition operations

First we must find the LCM of the denominators

which is x²

Therefore we have

=3x+4/x²

=(3x+4)/x²

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
