Answer:

47

Step-by-step explanation:

Step-by-step explanation:

(Base1 + Base2)/2 = midsegment

1. ((2x+15) + (6x-37))/2 = 3x+5

2. (8X-22)/2 = 3x+5

3. ((8x-22)/2))2 = (3x+5)2

4. 8x-22=6x+10

5. 2x-22=10

6. 2x-22+22=10+22

7. 2x=32

8. x=16

Now that you have solved for X add the value to line RS

RS = 2(16) + 15

RS = 32 + 15

RS = 47

Answer:

x = \frac{7+\sqrt{47}\times i }{4}

Step-by-step explanation:

<u>To solve quadratic systems,we always substitute one variable in terms if the other and then solve the equation.</u>

x + 2y = 6                                 ---------------(1)

y - 5 = (x-2)^{2}         ---------------(2)

y = (x-2)^{2} + 5         ---------------(3)

Substitute (3) in (1) ,

x + 2( (x-2)^{2} + 5 ) = 6

(a + b)^{2} =a^{2} + 2ab + b^{2}

x + 2( x^{2} - 4x + 4 + 5 ) = 6

2x^{2} - 7x + 12=0      --------------(4)

The roots of the quadratic equation ax^{2}  +bx+c is

x = \frac{(-b) + \sqrt{(-b)^{2}-4 \times ac }  }{2 \times a}  -----------(5)

According to equation (5),solution of (4) is

x =  \frac{7 + \sqrt{(-7)^{2}-4 \times 24 }  }{2 \times 2}

x =  \frac{7+\sqrt{49-96}}{4}

x = \frac{7+\sqrt{47}\times i }{4}
