Step-by-step explanation:
7. 180 -92 -67 =21. 180-21 = 159
8.180-144 = 36 + 94 = 130 180-130 = 50
It’s 1, anything to the zero power is one.
First, set these expressions equal in an equation. solve for x, then multiply x by 3 because there are 3 sides. the perimeter is 12
Answer: 11
Step-by-step explanation:
