R = 24.4 / 2 = 12.2

A = 3.14 (12.2)^2
A = 3.14 (148.84)
A = 467. 36

hope it helps

Given that S is the centroid of triangle MNO, find SQ. A. 4. B. 5. C. 10. D. 15

Angelina_Jolie [31]

First, we need to calculate for x. Since,
MP = PN
Thus,

3x-4 = x+4
2x = 8
x = 4

<span>Next, we calculate for MS </span>
MS = 2x + 2 = 10

Since, MS = 2SQ
10 = 2SQ
Then,
SQ = 5 units

Therefore, the correct answer is B.

Given the expression: 3x10 − 48x2

BartSMP [9]

Factorization involves representing an expression with smaller terms.

<em>When the greatest common factor is factored out, the equivalent expression is: </em> $3x^2(x^8 - 16)$ <em>.</em>
<em>The complete factored expression is: </em> $3x^2(x^4 - 4)(x^4 + 4)$ <em />

The expression is given as:

$3x^{10} -48x^2$

The GCF of $3x^{10}$ and $48x^2$ is $3x^2$ .

So, we have:

$3x^{10} -48x^2 = 3x^2 \times x^8 - 3x^2 \times 16$

Factor out $3x^2$

$3x^{10} -48x^2 = 3x^2(x^8 - 16)$

To factorize the expression completely, we express $x^8$ and $16$ as squares.

So, we have:

$3x^{10} -48x^2 = 3x^2((x^4)^2 - 4^2)$

Apply difference of two squares

$3x^{10} -48x^2 = 3x^2(x^4 - 4)(x^4 + 4)$

So, the complete factor of $3x^{10} -48x^2$ is $3x^2(x^4 - 4)(x^4 + 4)$
