The property is distributive
Answer:
Step-by-step explanation:
The measurements of a quadrilateral will add up to be 360. Additionally, we know these two triangles created within the parallelogram will be congruent, so their corresponding angles will also be congruent by CPCTC.
(44 * 2) + (105 * 2) + (31 * 2) = 360

1)
3x^-1y^2x^3y^-1
when base are same powers add
3x^(-1+3)y^(-1+2)
3x^2y
2)
(-3) -(2)(-4)/(-2)-(-1)
(-3)+8/-2+1
-3+8/-1
5/-1
