Alexxandr [17]

Answer: 1 ⁸/₂₁ litres

Step-by-step explanation:

First find a common multiple to enable you add them up:

= 21

21 will be the denominator.

Multiply each numerator by the number you get when you divide 21 by the denominator.

= 21/3 = 7

= 7 * 2 = 14

= 21/7 = 3

= 3 * 5

= 15

= \frac{14 + 15}{21} \\\\= \frac{29}{21}

= 1\frac{8}{21} litres

I really need help I’m very confused
Vaselesa [24]

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
