-8x^2+54x+140

-2(4x^2-27x-70)

Start by factoring -2 out of all three terms:


-8x2 + 54x + 140 => -2(4x^2 - 27x - 70)


Applying the quadratic formula: b^2 - 4ac becomes (-27)^2 - 4(4)(-70), or 1849.

Because this discriminant is +, this quadratic has two real, unequal roots. They are:


-(-27) plus or minus sqrt(1849) 27 plus or minus 43

x = ------------------------------------------------ = ---------------------------------- =

2(4) 8


= {70/8, -2}


Thus, -8x2 + 54x + 140 factors into -2(x+2)(4x-35)

Please help to prove parallelogram.​
tino4ka555 [31]

The question requests proof that WV = VR. See the definition of Mathematical proof and the explanation for the proof below.

<h3>What is a mathematical proof?</h3>

Mathematical proof refers to the steps of logical arguments which are given to show that a mathematical statement is true or correct.

<h3>What is the proof that WV = VR?</h3>

  • Note that SR ║ QT;

Reason: This is given. The image is a parallelogram.

  • Hence, ∠PSR  = ∠WVP
    Reason: Alternate angles formed by two parallel lines crossing each other
Hence, SV = PVReason: This is given by the annotation on the image
  • Therefore: ΔSVR ≅ PVW
  • Reason: They are formed by two parallel lines crossing each other.

Therefore if  ΔSVR ≅ PVW;

Then WV = VR.

QED.
