Factor the expression by taking out the GCF. 3x - 9x3

Sholpan [36]

Consider the expression $3x-9x^3.$ It consists of two terms:

$3x=3\cdot x$

and

$-9x^3=-3\cdot 3\cdot x\cdot x\cdot x.$

The common factors in these terms are $3$ and $x.$ Then

$GCF(3x,-9x^3)=3x.$

Taking out the GCF, you obtain

$3x-9x^3=3x(1-3x^2).$

Answer: correct choice is B.

The diameter of Jupiter is 142.984 Km. The surface area of Saturn is 59.9% the surface area of Jupiter. What is Saturn's diamete

Otrada [13]

Suppose that both planets are spherical. radius of Saturn =142984/2=71,492

Area of Jupiter = 4πr² ==>4π(71,492)² =6.4228 x 10^10

Area of Saturn ==>(6.4228 x 10^10)x(0.599) ==>3,84726 x 10^10

Radius of Saturn = 4πr² =3,84726 x 10^10==> r²=3,0219 x 10^10
and r √(,0219 x 10^10) = 174.000 km & D = 384,000 km
