Answer:</h3>
-y³ -6y²x +30
<h3>
Step-by-step explanation:</h3>
When parentheses are eliminated and the y variable placed first in each term, the expression simplifies to ...
... 15 -7y²x -y³ +y²x +15
Arranging like terms together, we have ...
... -y³ +y²x(-7 +1) +(15 +15)
... -y³ -6y²x +30
_____
The two different 3rd-degree terms can be expressed in either order. I have chosen to list the term with the largest exponent first. The expression could also be written with the same-degree terms in "lexicographical order", meaning the expression would be written ...
... -6xy² -y³ +30
The hikers 3 miles from the trailhead to the waterfall.
d1 = 3 miles
Then, the hikers made a right turn and hiked another 3 miles until they stopped for lunch.
d2=3 miles
We can solve the distance when they returned to the trailhead using Pythagorean theorem:
D ² =d1² + d2²
D² = 3² + 3²
D = 4.24
The distance is 4.24 miles.
Answer:
4 cm, if you subtract 9 from 13 you get four.
8 cubic cm equal to 8 milliliters. It does not equal 2.5 mm.
Alright my friend so basically if we subtract 5 from 71 we get 66 plus 8 would be 74 so we would have to drop the temp 3 degrees to get back to 71 so the answer will be option B. fall 3 degrees
