Step-by-step explanation:
x2 + 7x + 12
x2 + 4x + 3x + 12
x(x + 4) + 3( x + 4)
(x + 3) and (x + 4) are the factors
4x2 + 6x + 2
4x2 + 4x + 2x + 2
4x (x + 1) + 2(x + 1)
(x + 1) and (4x + 2) are the factors
R12 because you multiply the numbers but keep the (r)
D/H = 0.25
18/H = 0.25/1
Cross multiply and solve for H
Answer:
The change of concentration surely made the difference since the last drink contained more juice with respect to the water
Step-by-step explanation:
The concentration of a drink
