Answer:

2x^3 + 5x^2 - x - 6

Step-by-step explanation:

[NOTE]

I am assuming x2 is x^2, if I am wrong about that then please notify me in the comments

[END NOTE]

The parenthesis are implications that we multiply the numbers within them.

Therefore, multiply.

(2x)(x2)

2x^3

(2x)(x)

2x^2

2x^3 + 2x^2

(2x)(-2)

-4x

2x^3+2x^2-4x

(3)(x2)

3x^2

2x^3+2x^2-4x+3x^2

(3)(x)

3x

2x^3+2x^2-4x+3x^2+3x

(3)(-2)

-6

2x^3+2x^2-4x+3x^2+3x-6

Now combine like terms, meaning the numbers with the same endings, you cannot add a number with different exponents and adding numbers with and without a variable.

2x^3 + 5x^2 - x - 6

A triangle has squares on its three sides as shown below. What is the value of x? Three squares having side lengths 3 cm, x cm,
Pani-rosa [81]

Answer:

The value of x is 5 centimeters.

Therefore, option 3 is correct.

Step-by-step explanation:

A triangle has three sides 3,x and 4 cms

Since the triangle is right angle triangle  so, it will follow the Pythagoras theorem:

hypotenuse^2=side^2+side^2    (1)

We have been given three sides x,3 and 4

On substituting the values in (1) we get:

x^2=3^2+4^2

x^2=9+25

\Rightarrow x=5

Hence, the value of x is 5 centimeters.

Therefore, option 3 is correct.

Please look at the attachment for the figure.
