xxTIMURxx [149]

A quadratic equation is an equation whose leading coefficient is of the second degree. The correct options are A, B, and E.

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c. The Roots of the quadratic equation:

x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

The complete question is:

Patel is solving 8x2 + 16x + 3 = 0. Which steps could he use to solve the quadratic equation? Select three options.

8(x2 + 2x + 1) = –3 + 8

x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot

x = –1 Plus or minus StartRoot StartFraction 4 Over 8 EndFraction EndRoot

8(x2 + 2x + 1) = 3 + 1

8(x2 + 2x) = –3

If we simplify the given options, then the option that is correct is,

A.) 8(x² + 2x + 1) = –3 + 8

     8x² + 16x + 3 = 0

B.) 8x² + 16x + 3 = 0

x = \dfrac{-16\pm\sqrt{16^2-4(8)(3)}}{2(8)}\\\\x = -1 \pm \dfrac{\sqrt{10}}{4}\\\\x = -1 \pm \sqrt{\dfrac{10}{16}}\\\\x= -1 \pm \sqrt{\dfrac{5}{8}}

E.) 8(x² + 2x) = –3

8x² + 16x + 3 = 0

Hence, the correct options are A, B, and E.

The volume of clay used to build a cylindrical pillar with a height of 9 centimeters is 324π cubic centimeters. What is the area
elena-s [515]
Given:
V = 324 cu cm
h = 9 cm

Since the formula for the volume of a cylinder is V = AreaBase*height

AreaBase = V/height = 324cu cm/ 9 cm
AreaBase = 113.04 square centimetres

Therefore, the area of the pillar in square centimeters is 113.04.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
