Answer:

x = -1, 0, 2

Step-by-step explanation:

p(x) = 5x³ − 5x² − 10x

Factor the greatest common factor:

p(x) = 5x (x² − x − 2)

Now factor the quadratic. You can use the AC method, the quadratic formula, the rational root test, or trial and error.

p(x) = 5x (x − 2) (x + 1)

Finally, set each factor equal to 0 and solve for x.

5x = 0 → x = 0

x − 2 = 0 → x = 2

x + 1 = 0 → x = -1

Convert 27/20 to a decimal

Tatiana [17]

27/20

= 20/20 + 7/20

= 1 + 7/20

= 1.00 + 0.35

= 1.35

------

List of values to remember (extras):

0.05 = 1/20 = 5%
0.10 = 1/10 = 10%
0.15 = 3/20 = 15%
0.20 = 1/5 = 20%
0.25 = 1/4 = 25%
0.30 = 3/10 = 30%
0.35 = 7/20 = 35%
0.40 = 2/5 = 40%
0.45 = 9/20 = 45%
0.50 = 1/2 = 50%
0.55 = 11/20 = 55%
0.60 = 3/5 = 60%
0.65 = 13/20 = 65%
0.70 = 7/10 = 70%
0.75 = 3/4 = 75%
0.80 = 4/5 = 80%
0.85 = 17/20 = 85%
0.90 = 9/10 = 90%
0.95 = 19/20 = 95%
1.00 = 1 = 100%

The figure below is a regular octagon with a side length of 8 inches.

Masteriza [31]

Answer:

309in²

Step-by-step explanation:

Area of an octagon is expressed as;

A=2(1+√2)a²

a is the side length of the octagon

Given

a = 8

Substitute into the formula

A = 2(1+√2)(8)²

A = 2(1+√2)(64)

Expand

A = 2(64+64√2)

A = 128+128√2

A = 128+128(1.414)

A = 128+181.01

A = 309in²

Hence the area of the octagon is 309in²

A cube is painted so that one side is blue, two sides are red, and three sides are green. How many different such cubes can be p

Angelina_Jolie [31]

Answer:

So there are 3 distinct cubes.

Step-by-step explanation:

There are total six sides of the cube.

if we observe the given data and fix the sides of the cube by the color

So,

let suppose,

Blue color is painted on the top side of the cube

Now, we have left 5 sides

as per the information 2 sides are painted by Red color

let suppose,

1 Red color is painted on bottom side And 1 is on side

Now, we have left 3 sides

And 3 sides are green as per the given information.

1 green color painted on the adjacent side of the red side

1 green side is opposite of red side.

and 1 opposite of green side.

Now all side are colored and if we observe the above scenario

All other possibilities can be rotated to one of these.

So there are 3 distinct cubes.
