PEMDAS!
1. 7-14=-7
2. -1*-7 = 7-5=2
3. 18-2-9 = 7
There are markings given in the diagram.
(Angle) ∠A and ∠D are =
(Side) AC and DB are =
(Side) In a trapezium, the opposite sides are equivalent, meaning AB and DC are =
So you got side, angle, and another side.
You can form the SAS (Side-Angle-Side) similarity theorem.
You can also use the reasons above to make a Statement-Proof table
Im not 100% sure but I believe it is 4/14 chance or 3.5
I'm thinking n would be -2 but when I add it stops at 11 and when I put -3 in its place it says 14 so I'm guessing maybe -2.4
The mixed number in the equation 17/3=5r2 would be 5 2/3=5r2.
