Answer:
4 rows of 7 plants each
Step-by-step explanation:
To find the number of plants in each row between 5 and 12 requires us to find the factors of the total 28.
28 has factors 1,28 and 2,14 and 4,7. Only 4,7 has a number between 5 and 12. There are 4 rows of 7 plants.
We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.
For d and e are correct
I really hope this helps! Have an awesome day:D
Answer:
4 x 3 - 1 x 20 = -8

Distribute 2 to 3t and 4, and 6 to t and 2
2(3t + 4) = 6t + 8
6(t + 2) = 6t + 12
Combine like terms:
6t + 8 + 6t + 12 = 12t + 20
12t + 20 is your answer
hope this helps
