X + 2y = -3 x - y = -12
Nastasia [14]

Answer:

x = -9, y =3

Step-by-step explanation:

x + 2y = -3

x - y = -12

Subtract to two equations to eliminate x

x + 2y = -3

-x + y = 12

---------------------

   3y = 9

Divide each side by 3

3y/3 = 9/3

y = 3

Now we can find x

x-y =-12

x - 3 = -12

Add 3 to each side

x-3+3 = -12+3

x = -9

Find the length of the third side. If necessary, write in simplest radical form
katrin [286]

HERE,

the \huge{\triangle}is a right angle traingle.

length of one side=\bold{ 1  } 

length of another side =\bold{\sqrt{3}  } 

so,

the length of third side=

  • \bold{\sqrt{(1)^{2} +({\sqrt{3}})^{2}}   } 

  • \bold{\sqrt{1+3}   } 

  • \bold{\sqrt{4}   } 

  • {\huge{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{2}}}}}}

\therefore,the length third side of the traingle is 2.

X(x+5)+6(x+5)=(x+5)(?)<br> help
Karo-lina-s [1.5K]

Answer:

x = -25/12 or x = -0.2

Step-by-step explanation:

x(x+5)+6(x+5)=(x+5)

Distribute

x^2 + 5x + 6x + 30 = x + 5

Combine

x^2 + 11x + 30 = x + 5

Subtract 1x from both sides

x^2 + 10x + 30 = 5

Subtract 30 from both sides

12x = -25

Divide 12 on both sides

x = -25/12 or -0.2

Hey can you please help me posted picture of question
Debora [2.8K]
We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:

x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a}

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15

Using the values, we get:
x= \frac{11+- \sqrt{121-4(2)(15)} }{2(2)} \\  \\ &#10;x= \frac{11+-1}{4} \\  \\ &#10;x=3, x= 2.5

So, the correct answer to this question are option B and D
