Answer: 12
Step-by-step explanation:
18−2(10+8)/6
=18−(2)(18)/6
=18−36/6
=18−6
=12
Each X and Y in the equations don't have a number in front of them so they are all considered 1.
D = 1*(-1) - 1*(-1) = -1 -1 = -2
The answer is -2
(5-5) x
It is different because when you distribute the x it will make it 5x-5x while all the other equations are 5-5x
Answer:
9^2= 81, √25= 5, 21^2= 441, √4= 2, √144= 12, 16^2= 256, √625= 25, (-11)^2=121
