Answer:
Step-by-step explanation:
Density D=M/V
where Volume of earth =(4/3)pi r^3
therefore density D=M/(4/3)pi r^3
r= 3√3m/4piD
Answer:
c and F
Step-by-step explanation:
2x² + 6x - 10 = x² + 6
2x² - x² + 6x - 10 - 6 = 0
x² + 6x - 16 = 0
(x + 8)(x - 2) = 0
x = -8
x = 2
so C and F

Factoring
This will give us the two remaining roots
Answer:
x+9
Step-by-step explanation:
If we use syntetic division we get that
5(∛x) + 9(∛x)
= ∛x (5 + 9)
= 14∛x
Answer is the third option
14∛x
