Hello there!

(x - 3)(x + 9) = -27
x² + 6x - 27 = -27
x² + 6x = -27 + 27
x² + 6x = 0
Factorize
x(x + 6) = 0
Now all we have to do is set the factors equal to 0
x = 0 or x+6 = 0
x = 0 or x = -6
Answer : x = 0 or x = -6

I don't know what the options they give you. But if you see 0 or 6 choose it.

I hope this help!

The figure is made up of a cylinder and a cone. What is the volume of the composite figure? Use 3.14 for Pi. Round to the neares
Delvig [45]

Answer:

The volume of figure is 310.86 cm³

Step-by-step explanation:

First, you have to calculate the volume of cone and cylinder seperately by applying the formulas :

Cone,

v =  \frac{1}{3}  \times \pi \times  {r}^{2}  \times h

let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 9

v =  \frac{1}{3}  \times 3.14 \times  {3}^{2}  \times 9

v = 84.78 \:  {cm}^{3}

Cylinder,

v = \pi \times  {r}^{2}  \times h

let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 8

v = 3.14 \times  {3}^{2}  \times 8

v = 226.08 \:  {cm}^{3}

Next, you have to add up both volumes as the figure are made from cone and cylinder :

v = 84.78 + 226.08

v = 310.86  \: {cm}^{3}
