Answer:
Step-by-step explanation:
The difference would be that for (-5)^2 you would have to do anything that was in the parenthesis first and then square it up, but for -5^2 you would just square it up immediately. In this specific case both outcomes would be the same result and the answer would be 25 since a negative times a negative is a positive. It would be the same because there is nothing in the parenthesis.
Answer:
81.9 Inches
Step-by-step explanation:
Used a calculator and formula to calculate the answer
Area of trapezoid = 1/2 (sum of parallel sides) × (perpendicular distance between them)
Area = 1/2 × (5.8+11.8) × 7.5
= 1/2 × 17.6 × 7.5
= 66 cm²
(sqrt(2)/2, -sqrt(2)/2) this is the answer
