Answer:
-3x + 11
Step-by-step explanation:
The best method to solve this problem is using distributive property.
2(x + 3) = 2x + 6
5(x - 1) = 5x - 5
(2x + 6) - (5x - 5)
Open parenthesis, change the negative sign in the parenthesis to a positive sign because there is a negative sign in front.
2x + 6 - 5x + 5 = -3x + 11
Hope this helps :)
The solution to the system is (-2,-8)
The sides of the rectangle are aligned with the coordinate axes, so the dimensions of the rectangle are easily determined to be 4 -(-7) = 11 units by 1 -(-1) = 2 units. As with any rectangle, the area is the product of length and width.
The area is 11*2 = 22 square units.

The probability is 1/1024.
Each tetrahedron has a 1/4 chance of landing on 3, since there are 4 sides and only one of them is marked 3.
Each tetrahedron roll is independent, since no roll is affected by another.
This means we multiply the probabilities:
1/4(1/4)(1/4)(1/4)(1/4) = 1/1024
