Answer:
30 y
Step-by-step explanation:
We need to multiply 5 by 4y and 5 by 2 y
20y + 10y = 30y
You must realize that it depends on the function ...
something that you've kept hidden from us.
Right around 75 I would believe
The answer is 14/3 or 4 and 2 thirds
1) a = 2, b= 3, c=2,
2) x^2 -2x-4 (a = 1, b=-2, c =-4)
3) x^2+x+3 (a,b = 1, c = 3)
4) 7x^2+8x-4 (a=7, b=8, c=-4)
