Answer:
4320
Step-by-step explanation:
V = 2x^3 + 6x^2
x = 12
V = 2(12^3) + 6(12^2)
V = 2(1728) + 6(144)
V = 3456 + 864
V = 4320
For the equation Y value is -45.
First you have to set the fractions with an equal denominator
hint: numerator/denominator
all of the denominators go into sixty
1/10=6/60
1/4=15/60
1/5=12/60
2/15=8/60
then you will have to add the numerators
(6+15+12+8)/60 = 41/60
simplify if possible but it's not necessary for this one
