Factor completely<br> 486+108x+6x^2<br><br> Thank you!
viktelen [127]

Answer:

6(x + 9) (x + 9)

or

6 (x+9)^{2}

Step-by-step explanation:

468 + 108x + 6x^{2} \\6x^{2} +108x + 468

Greatest common factor of 6, 108, and 486:

6 x 1 = 6

6 x 18 = 108

6 x 81 = 486

GCF: 6

so:

6(x^{2} +18x +81)

x^{2} +18x + 81

factors to:

(x + 9) (x + 9)

because:

9 x 9 = 81

9 + 9 = 18

So:

It factors completely too:

6(x + 9) (x + 9)

or

6 (x+9)^{2}

Please help me now plz <br> I will mark you brainliest
Stella [2.4K]

Answer:

x=13

Step-by-step explanation:

The right side is a right triangle

The base is 1/2 of the bottom or 5

The height is 12 and the hypotenuse is x

We can use the Pythagorean theorem

a^2 +b^2 = c^2

5^2 +12^2=x^2

25+144 = x^2

169=x^2

Take the square root of each side

sqrt(169) = sqrt(x^2)

13=x
