Lets use quadratic formula:

x=\frac{-1+- \sqrt{1-4*2*6} }{4}= \frac{-1+- \sqrt{-47} }{4}= \frac{-1+-i \sqrt{47} }{4}
x₁=\frac{-1+i \sqrt{47} }{4}
x₂=\frac{-1-i \sqrt{47} }{4}

2x² + x + 6 = 0
x = <u>-(1) +/- √((1)² - 4(2)(6))</u>
                    2(2)
x = <u>-1 +/- √(1 - 48)</u>
                 4
x = <u>-1 +/- √(-47)
</u>               4
x = <u>-1 +/- i√(47)
</u><u /><u />               4<u>
</u>x = <u>-1 + i√(47)</u>              x = <u>-1 - i√(47)
</u><u />              4                                 4
x = -0.25 + 0.25i√(47)      x = -0.25 - 0.25i√(47)

Given: PQ = RS, QR = 11, QS = x + 19, and RS = 2X. Find QS.<br> Can someone help
nalin [4]

QS =25

Step-by-step explanation:

QR + RS = QS

18 + (x-11) =2x-11

7 +x =2x -11

18=x

Plug in x

2(18) -11

36-11

QS=25

18 + (18-11) = 2(18)- 11

18+ 7 = 36 -11

25= 25

True

Answer:

QS + QR > RS

QR + RS > QS

RS + QS > QR

Step-by-step explanation:

Hope it helps you!

Twenty four(24) minus 1/3
frosja888 [35]
23 and 2/3
you have 24 and you are taking away 1/3 of a whole
1/3 is equal to .333333333 repeating, as a decimal
therefore 1/3 is less than 1
you are taking away 1/3 of 1 away from 24
1 is equal to 3/3
take away 1/3 and you are left with 2/3
3/3-1/3=2/3
2/3 + 23 (the number that you did not touch)
and you are left with 23 2/3
