1. statement- quadrilateral ABCD Reason- diagonal AEC
Answer:
（2,-4）
Step-by-step explanation:
-4＋2＝-2
10＋-4＝10-4＝6
3^(-2) = 1/(3^2) = 1/(3*3) = 1/9
The rule used here is x^(-y) = 1/(x^y) to make the exponent positive.
3^2 turns into 3*3 because the exponent 2 tells us how many copies of the base '3' to multiply out.
