I think it’s 7,3 because u go side ways then go down!
You divide 3 on both sides then you equation is the square root of -4x-4 =4 and you square the number on both sides because u need to do the same things on both sides and you get -4x-4=16 subtract by 4 on boyh sides to get -4x=20 and divide by -4 on both aises to get x=-5
I hope this helped i know this explanation is a bit wonky
It’s line always goes in both directions
If 2 cm = 4 feet then 1 cm = 2 feet
8 cm ⇒ 16 feet
6 cm ⇒ 12 feet
So it is 16 length and 12 width
X = 18/sin35° = 18/0.5736 ≈ 31.4
