Your answer would be either A...or D.
Answer:
4 hours
Step-by-step explanation:
Write an equation:
30x+97=217
Subtract 97 on both sides
30x=120
divide 30 on both sides to isolate the variable
x=4
Answer:
B) x = (-5 + √10)/3 and (-5 - √10)/3 is the answer.
Step-by-step explanation:
3x² + 10x + 5 = 0
a = 3
b = 10
c = 5
Finding the Discriminant (D),
D = b² - 4ac
D = 10² - 4 × 3 × 5
D = 100 - 60
D = 40
√D = 2√10
Using quadratic formula,
x = (-b ± √D)/2a
x = (-b + √D)/2a
x = (-10 + 2√10)/2 × 3
Taking out the common factor 2,
x = (-5 + √10)/3
Similarly,
x = (-b - √D)/2a
x = (-10 - 2√10)/2 × 3
x = (-5 - √10)/3
Hi there Kay,
The correct answer according to a cylinder calculator would be 339.29 cubic inches but the closest answer you have would be 339.12 cubic inches
