Find the values for x and y in rectangle SLIM.

skelet666 [1.2K]

Answer:

x = 25

y = 65

Step-by-step explanation:

(I did it on Math Nation)

180 = 130 + 2x

50 = 2x

x = 25

180 = 50 + 2y

130 = 2y

y = 65

Answer:

Step-by-step explanation:

Draw a picture. Seriously, this time you need to, so you can see that PS is the hypotenuse of a right triangle with legs of length 3 and 4 .

PS = √(3² + 4²) = 5

Perimeter = PQ + QR + RS + PS = 9 + 4 + 6 + 5 = 24 cm

Pemfaktoran dari 2x²+5x-18<br><br>

Harrizon [31]

We can factor a polynomial by finding its roots. In particular, a quadratic equation has (at most) two roots $x_1,\ x_2$ , which would allow us to write the polynomial as

$p(x)=a(x-x_1)(x-x_2)$

To find the solutions, we can use the quadratic formula

$x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a} = \dfrac{-5\pm\sqrt{169}}{4} = \dfrac{-5\pm13}{4}$

So, the two solutions are

$\dfrac{-5+13}{4} = 2\quad\text{and}\quad\dfrac{-5-13}{4} =-\dfrac{9}{2}$

And so we can factor the polynomial as follows:

$2x^2+5x-18=2(x-2)\left(x+\dfrac{9}{2}\right)$
