The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
Answer:
x = 3

Answer:
Volume of cone = 130 cm³
Step-by-step explanation:
Given:
Volume of cylinder = 390 cm³
dimensions of cylinder = dimensions of cone
Find:
Volume of cone
Computation:
Volume of cylinder = πr²h
390 = πr²h
124.090909 = r²h
So,
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)(22/7)r²h...........[124.090909 = r²h]
Volume of cone = (1/3)(22/7)(124.090909)
Volume of cone = 130 cm³
X, X+2, and X+4 are the three odd integers.
2(X)+(X+4)=25 represents the problem.
2X+X+4=25
3X+4=25
3X=25-4
3X=21
X=7

Answer:
14.9 cm
Step-by-step explanation:
To find c using the Law of Sines, you must know angle C. That is found from ...
C = 180° -A -B = 180° -150° -12° = 18°
Then the law of sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)
c ≈ 14.9 cm
