Step-by-step explanation:
2x^2 -2x-12 = 0
Factor out 2
2(x^2 - x -6) = 0
Factor inside the parentheses
2( x-3)(x-2)=0
Using the zero product property
x-3 =0 x-2=0
x=3 x=2
The graph crosses the x axis when x=3 and x=2
Answer:
E
Step-by-step explanation:
19) Amount of oil in = amount of oil in final product
.025(x) + .09(40-x) = .055(40) (x = 2.5% amt 40 - x = 9% amt)
x = 21.54 L of 2.5 % then 9% = 18.46 L
To see which one is lesser, it is necessary to convert one to the unit of the other. This can be done using the following relation: 1 L = 1000mL
Converting 250mL to L:
250 mL * (1 L / 1000 mL) = 0.25 L.
Therefore, the amount 250 mL is the lesser of the two.
