Answer:
3. - 8n² -8n + 3
Step-by-step explanation:
(4n^4 - 8n +4) - (8n² + 4n^4 +1)
Firstly, open the brackets.
= 4n^4 - 8n +4 - 8n² - 4n^4 - 1
Now, group like terms.
= 4n^4 - 4n^4 - 8n² -8n - 1 + 4
4n^4 - 4n^4 cancel out with each other since one is negative and the other is positive. So we're left with - 8n² -8n - 1 + 4
= - 8n² -8n - 1 + 4
= - 8n² -8n + 3
Answer:
14 cm
Step-by-step explanation:
There are 2 equal sides of 13 cm, thus the third side is
third side = perimeter - 13 - 13 = 50 - 26 = 14
No guarantee that there will enough hotdogs for the buns, we must find the common multiple between the usual number of hot dogs and buns in each package.
Since we're looking for the smallest common multiple between 8 and 10, we can use the method shown below to compute for the least common multiple.
8 = 2³
10 = 2 x 5
LCM = 2³ x 5 = 40
To purchase 40 hot dogs and buns, you need to buy 5 packages of buns and 4 packages of hot dogs.
Answer:
Hotdog: 4 packages
Buns: 5 packages
Answer:
20.56 cm
Step-by-step explanation:
5y+2(3y-1)=__y-(y+2)
5y+6y-2=__y-y-2
11y-2+2+y=__y
12y=___y
so 12
