Answer:
25x² − 20x + 4
Explanation:
(5x − 2)²
= (5x + −2)(5x + −2)
= (5x)(5x) + (5x)(−2) + (−2)(5x) + (−2)(−2)
= 25x² − 10x − 10x + 4
= 25x² − 20x + 4
8.2*10^-5 can be also written as 0.000082, in standard notation.
Hope this helps.

Answer: 2 Fahrenheit per hour
Step-by-step explanation:
From the question, we are given the information that the outside temperature decreases by 7 fahrenheit in 3 1/2 hours.

= 7 ÷ 7/2
= 7 × 2/7
= 2 Fahrenheit per hour
