Answer:
8by + 2ax - 4bx - 4ay
Step-by-step explanation:
I assume you mean expand so:
(a - 2b)(3x - 5y) + (2b - a)(x - y)
3ax - 5ay - 6bx + 10by + 2bx - 2by - ax + ay
Now collect like terms:
2ax - 4ay - 4bx + 8by
This is your answer but in a better order:
8by + 2ax - 4bx - 4ay
Answer:
10/4
Step-by-step explanation:
Randomthing2143 is right
204/6 = 34 trees a day. 340-204 =136 trees left to plant. 136/34 = 4 4 days
t = mr^2/3
Divide both sides by r^2/3
m = t / r^2/3
