1) add.
for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3
2) subtract
for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3
3) change
for example 3 - (- 2) = 3 + 2
4) -10
the sum is -10.25, which is closest to -10
Answer:
1) add
2) subtract
3) change
4) -10

Solution:
Polygon ABCDEFGH is dilated by a scale factor of 3.4 with the origin as the center of dilation to produce polygon A'B'C'D'EFG'H'.
As, when a polygon is dilated , the two pre image and image are similar to each other.
Also, similar shapes have same ratio of their corresponding sides length.
→Pre image (Polygon ABCDEFGH) ~Image ( A'B'C'D'EFG'H').
Dilation factor >1, equal to 3.4.
Length of segment A'H'=3.4 AH
