Answer:
10: -11n^5
12: 6k^2 -6k+7
Step-by-step explanation:
Ok so what your gonna do is add or subtract the ones with the same exponent.
so -15+4= -11 since they are both n^5 you can add them so your answer is:
-11n^2
now you have 8k^2-k-5k+7-2k. so you are gonna rearrange them so the same exponents are together.(keep the sign in front in front, if no sign it is positive)
8k^2-2k^2-5k-k+7
add like exponents
6k^2-6k+7
Answer:
Total
Step-by-step explanation:
A percent bar graph compares the amount in each category to the total amount (sum of all categories) as a percentage.
Answer:
Step-by-step explanation:
a. scalene : Reason: all angles and sides are different measurements.
f. acute
: all the three angles are acute (Less than 90)
If you have built 25 cars, and they are 36 dollars per, then multiply 25 and 36 for the amount of money. This will result with 25*36=900. Since we already have 900 dollars worth, we subtract that from the goal of 1620, leaving us with 1620-900=720. Now, divide this by the price per car for the amount of cars needed to get to this goal. 720/36=20 cars
Hope this helps!
Answer:
I think it's 1 1/4 liters of paint for one door
Step-by-step explanation:
First you have to turn it to an improper fraction
1.) 1 3/5 = 8/5
Then you have to proportion the fraction with the 2 liters (L=liters)
2.) 2/(8/5)
= 10/8 L
3.) Next you convert the fraction to a mixed number
10/8 L --> 8/8 + 2/8 = 1 1/4 L
