You guys can see that I have very low battery so I need someone to help me with this please

A

Step-by-step explanation:

First, add 4 to both sides to get 16

then, divide by two to get 8

keep the inequality the same, because you were dividing by a positive number

A. X ≤ 8

Step-by-step explanation:

Let's solve your inequality step-by-step.

2x−4≤12

Step 1: Add 4 to both sides.

2x−4+4≤12+4

2x≤16

Step 2: Divide both sides by 2.

2x     16

≤

2       2

x≤8

i'm assuming it's looking for the missing length, which should be 4cm

hope this !
