Which equation is quadratic in form? 2(x 5)2 8x 5 6 = 0 x6 6x4 8 = 0 7x6 36x3 5 = 0 4x9 20x3 25 = 0
Amiraneli [1.4K]

The equation that fits the standard form of a Quadratic equation is 2(x + 5)² + 8x + 5 +  6 = 0 which can be re-written as 2x² + 28x + 61 = 0.

<h3>What is a Quadratic Equation?</h3>

Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

From the given data, we check which of them fits the standard form of a quadratic equation.

  • 2(x + 5)² + 8x + 5+  6 = 0
  • x⁶ + 6x + 4  + 8 = 0
  • 7x⁶ + 36x³ + 5 = 0
  • 4x⁹ + 20x³ + 25 = 0

2(x + 5)² + 8x + 5 +  6 = 0

2( (x(x+5) + 5(x+5) ) + 8x + 5 +  6 = 0

2( x² + 5x + 5x + 25 ) + 8x + 5 +  6 = 0

2( x² + 10x + 25 ) + 8x + 5 +  6 = 0

2x² + 20x + 50 + 8x + 5 +  6 = 0

2x² + 20x + 8x + 50 + 5 +  6 = 0

2x² + 28x + 61 = 0

Therefore, the equation that fits the standard form of a Quadratic equation is 2(x + 5)² + 8x + 5 +  6 = 0 which can be re-written as 2x² + 28x + 61 = 0.

What is the volume of a cube that has a side length of 5 centimeters? A cube with side lengths of 5 centimeters. Recall the form
Mashutka [201]

Answer:

125 cm^3

Step-by-step explanation:

To calculate this volume, we make use of the formula for calculating the volume of a cube.

Mathematically, this is equal to L^3 where L is the length of a side of the cube.

plugging the value of 5 into the equation, the volume will be 5 * 5 * 5 = 125 cm^3

Write an equation of the line shown. Then use the equation to find the value of x when y=150
Kisachek [45]

Answer:

Step-by-step explanation:

x = 12

Step-by-step explanation:

The slope-intercept form formula, , can be used to write an equation for the line.

Where,

m = slope =  

b = y-intercept, which is the point at which the line intercepts the y-axis. At this point, x = 0.

Let's find the slope (m) using the coordinates of the two points given, (0, 30), (3, 60).

Let,

y-intercept of the line, b = 30

Equation for the line would be:

Using the equation, find x when y = 150.

Simply substitute the value for y in the equation to find x.

Subtract 30 from both sides

Divide both sides by 10

x = 12
