To find the parameter you have to add the length and the width and multiply by two
And your example long is the length and wide is the width so add it and times two answer is seven
Because the semi circle is too which is what it's inside but the answer is still seven
if I'm just good at math I might be able to help you
Answer:
x = 51/6 or 17/2
<u>Step-by-step explanation:</u>
9( x-3) = 3 (x + 8)
Distribute
9x - 27 = 3x + 24
Add 27 to both sides
9x = 3x + 51
Subtract 3x from both sides
6x = 51
Divide both sides by 6
x = 51/6 or 17/2
