Add and subtract the rational expressions. 7x+5/x-1 -(8x1/x-1+2x-4/x-1) Which statements are true about the process for adding and subtracting the rational expressions? Select three options. 1. The expression is not defined when x = –1. The first step in the simplification is . 2. The denominator of the fully simplified expression will be x – 1. 3. The numerator of the fully simplified expression will be –3x. 4. The numerator of the fully simplified expression will be –3x + 10.

2. The denominator of the fully simplified expression will be x – 1.

4. The numerator of the fully simplified expression will be –3x + 10.

Step-by-step explanation:

Given the rational expression

Let us first simplify before making our deductions.

Opening the brackets

Taking LCM

Opening the brackets and simplifying

The following statements are therefore true:

2. The denominator of the fully simplified expression will be x – 1.

4. The numerator of the fully simplified expression will be –3x + 10.

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
