Answer:
14
Step-by-step explanation:
-392=28q
-392÷28=14
Let x = your number.
5x = x^2 - 14. To figure out the number, we have to first subtract 5x from each side.
0 = x^2 - 5x - 14. Factor.
0 = (x - 7) (x + 2). Set both terms to 0.
(x - 7) = 0. Add 7 to each side.
x = 7. You're looking for the negative value so this isnt the right one.
Set the other term (x + 2) equal to 0
(x + 2) = 0. Subtract 2 from each side.
x = -2
The negative solution for your number is -2
Answer:
C. 6m
Step-by-step explanation:
The formula for the volume of a cone: V = πr²h/3
Use this formula to solve for the height (isolate h).
226 = (3.14)(6)²h/3 (Given)
226 = (3.14)(36)h/3 (Squared 6)
226 = 113.04h/3 (Multiplied like terms)
678 = 113.04h (Multiplied 3 on both sides)
h = 5.997876858 ≈ 6 (Divided 113.04 on both sides)
Answer:
Answer = 140
Step-by-step explanation:
360 = 9x + 14x + 4x + 90
360 - 90 = 27x
270 = 27x
x = 270 / 27
x = 10
14 x 10 Angle F
Measure of angle F = 140
