A because 3m + 2 doesn’t match -3m +2. All the -3m +2 equations are the same except they are in a different order.
Answer:
8.2786 x 10 to the second power, 7.313 x 10 to the second power
Step-by-step explanation:
24, because you can just multiply 4 by 6 which is 24
Answer:
47 ducks and 7 cows
Step-by-step explanation:
Ducks have 2 legs and cows have 4 legs.
If all the animals are ducks,
number of legs= 54(2)= 108
Difference in number of legs= 122 -108= 14
Difference in no. of legs per animal= 4 -2 = 2
Number of cows=14 ÷2 = 7
Number of ducks= 54-7= 47
Thus, he have 47 ducks and 7 cows.
Let's check:
Total number of feet= 7(4)+ 47(2) = 122 ✓
You could also first assume that all the animals are cows. The answer would be the same.
Take out the largest common number
In this case is 6
6(3x + y)
hope this helps
you can factor 6 out of both
