-7, -3, 0 and then 5 would be the order from least to greatest.
Answer:
<u>It took Albert 2 1/2 hours to ride to the park</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Speed of Albert to the park = 12 mph
Speed of Albert back home = 20 mph
Total time of the round trip = 4 hours
Distance each way = 30 miles
2. How long did the ride to the park take?
Let's recall that the formula of speed is:
Speed = Distance/Time, therefore Time = Distance/Speed
Time it took Albert to ride to the park = 30/12
Time it took Albert to ride to the park = 5/2 = 2 1/2 hours
Time it took Albert to ride back home = 30/20
Time it took Albert to ride back home = 3/2 = 1 1/2 hours
<u>It took Albert 2 1/2 hours to ride to the park</u>
Our first expression is . Upon distributing the exponent 4 on all the terms, we get:
Therefore, your answer is correct for this part. :)
Second expression is . Upon distributing the exponent -2 on all the terms, we get:
Your second answer is correct too.
Our third expression is . Upon distributing the exponent 2 on all the terms, we get:
This one is not correct. Your answer would have been correct, if the exponent were -2 instead of 2 in this part.
Our forth and last expression is . Upon distributing the exponent -5 on all the terms inside the parenthesis, we get:
Therefore, your answer for this part is also correct.
Looking at your work, I don't think you made a mistake in number 3 also, probably mis-typed the question while writing here :)
