Parralel or most likely symmetrical
For x = 7 + (-1) = 6 -> 6/2 = 3
For y = -5 + (-2) = -7 -> -7/2 = -3.5
Midpoint(3, 3.5)
6 because 18+6=24+6=30+6=36
Answer: 2 grams
Step-by-step explanation:
Use the formula a squared plus b squared =csquared in this case you will come out with an equation like this
3sqaured + bsqaured =12squared
9+bsqaured =144
144-9= b= 135
B=approximately 11.5
