Answer:
You didn't include the question.
Step-by-step explanation:
Your answer is C) 2a² + 2b²
To find this we can just expand the brackets of (a - b)² and (a + b)², and then combine like terms:
(a - b)² = (a - b)(a - b) = a² - 2ab + b²
(a + b)² = (a + b)(a + b) = a² + 2ab + b²
Then when you combine like terms, you get (a² + a²) + (-2ab + 2ab) + (b² + b²), so the ab terms cancel out and you get left with 2a² + 2b².
I hope this helps!
Plug in 5 for t, while ignoring the +75.
Therefore, the anchor drops 12 m. every 5 seconds
When multiplying or dividing with negative and positive numbers, if the signs are the same, the result is positive...when the signs are different, the result is negative.
so a positive divided by a negative results in a negative...because the signs are different.
but if it was a negative divided by a negative or a positive divided by a positive the result would be positive because the signs are the same.
