Basically 1/2 equals 2 and times x equals 2x. X is a variable an unknown number so 2x +4 and that's how you get your answer
Answer: 8
Step-by-step explanation:
it's a rectangle, both the longer sides are the same and both the shorter sides are the same. so the opposite side has to equal 6, to get there we need to solve the equation, I did a few and ended up finding the correct answer to be 8. Since:
2*8-10=6
Therefore, both sides are now equal.
