30 + x thats yhur answer

or

(3x2 + 1) • (x + 3)

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2" was replaced by "x^2". 1 more similar replacement(s).

Step by step solution :Equation at the end of step 1 : (((3 • (x3)) + 32x2) + x) + 3 Step 2 :Equation at the end of step 2 : ((3x3 + 32x2) + x) + 3 Step 3 :Checking for a perfect cube :

3.1 3x3+9x2+x+3 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 3x3+9x2+x+3

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: x+3
Group 2: 3x3+9x2

Pull out from each group separately :

Group 1: (x+3) • (1)
Group 2: (x+3) • (3x2)
 -------------------
Add up the two groups :
 (x+3) • (3x2+1)
Which is the desired factorization

Polynomial Roots Calculator :

3.3 Find roots (zeroes) of : F(x) = 3x2+1
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 3 and the Trailing Constant is 1.

The factor(s) are:

of the Leading Coefficient : 1,3
of the Trailing Constant : 1

Let us test ....

P Q P/Q F(P/Q) Divisor -1 1 -1.00 4.00 -1 3 -0.33 1.33 1 1 1.00 4.00 1 3 0.33 1.33

Polynomial Roots Calculator found no rational roots

Final result : (3x2 + 1) • (x + 3) thats yhur answer

Encuentre el radio y el área de círculos cuya circunferencias tienen las siguientes medidas

Vadim26 [7]

Answer:

Los radios de los círculos son $r_{1} \approx 9.995$ , $r_{2} \approx 2.013$ , $r_{3} \approx 7.592$ , respectivamente.

Las áreas de los círculos son $A_{1} \approx 313.845$ , $A_{2} \approx 12.730$ , $A_{3} \approx 181.077$ , respectivamente.

Step-by-step explanation:

La circunferencia ( $s$ ) se calcula mediante la siguiente fórmula:

$s = 2\pi\cdot r$ (1)

Donde $r$ es el radio del círculo.

Una vez hallado el radio, se determina el área de la figura geométrica ( $A$ ) mediante la siguiente fórmula:

$A = \pi\cdot r^{2}$ (2)

Si conocemos que las circunferencias son $s_{1} = 62.8$ , $s_{2} = 12.65$ y $s_{3} = 47.7$ , respectivamente:

1) Radios de los círculos

$r_{1} = \frac{s_{1}}{2\pi}$ , $r_{2} = \frac{s_{2}}{2\pi}$ , $r_{3} = \frac{s_{3}}{2\pi}$

$r_{1} \approx 9.995$ , $r_{2} \approx 2.013$ , $r_{3} \approx 7.592$

2) Áreas de los círculos

$A_{1} = \pi\cdot r_{1}^{2}$ , $A_{2} = \pi\cdot r_{2}^{2}$ , $A_{3} = \pi\cdot r_{3}^{2}$

$A_{1} \approx 313.845$ , $A_{2} \approx 12.730$ , $A_{3} \approx 181.077$

What is the value of x in the proportion below? 1/2/4=x/28

True [87]

Answer:

depends on whether you meant (1/2)/4 or 1/ (2/4)

Step-by-step explanation:

1/2 x

---------- = -------------

4 28

Using cross products

1/2* 28 = 4x

14 = 4x

Divide by 4

14/4 = 4x/4

7/2 =x

If you meant

1 x

---------- = -------------

2/4 28

1 * 28 = 2/4 x

28 = 1/2 x

Multiply each side by 2

28*2 = 1/2x*2

56 =x

Choose all of the transformations that would change a triangle into one that is similar, but not congruent. Which transformation

Vsevolod [243]

You didn't supply a list. The so-called rigid transformations of translation, rotation and reflection create congruent triangles.

Generally it's dilation by a factor about a point is preserves similarity but not congruency. Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.
