Answer:
-69
Step-by-step explanation:
If he is below sea level it would be negative so -86+17=-69
Answer:
9.6 cm
Step-by-step explanation:
Since the scale factor is 3 (you can figure that out by dividing the larger side of the triangle by the one on the smaller triangle that is the same side) you would divide all other sides by 3 to find individual lengths.
9.6/3 = 3.2
7.2/3 = 2.4
We already know the other side, 4.
3.2 + 2.4 + 4 = 9.6cm
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 :)
