Answer:
x = -3,0,3
Step-by-step explanation:
5x^3 – 45x = 0
Factor out 5x
5x( x^2 - 9) =0
Factor inside the parentheses which is the difference of squares
a^2 - b^2 = (a-b)(a+b)
5x( x-3)(x+3) =0
Using the zero product property
5x =0 x-3=0 x+3 =0
x=0 x=3 x=-3
x = -3,0,3
Need mas
Find volume
- πr²h
- π(6)²(18)
- 36(18)π
- 2034.7cm³
Mass
As volume is same
Divide their densities to find ratio
- Gold /Silver
- 19.32/10.5
- 1.84 times heavier is gold
Answer: I believe the answer is b.
