What is the discriminant of 3x2 + 6x = 2?

Mathematics
1 answer:
Softa [21]3 years ago
5 0

Answer:

Discriminant is 60

Step-by-step explanation:

the discriminant of 3x^2 + 6x = 2

To find discriminant , first we write the equation in the form of

ax^2+bx+c=0

3x^2 + 6x = 2

Subtract 2 on both sides

3x^2 + 6x-2=0

a=3, b=6, c=-2

Formula for discriminant is b^2-4ac

Plug in the values

b^2-4ac=(6)^2-4(3)(-2)=60

Discriminant is 60

The figures below are similar.
Dafna1 [17]

Answer:

  a) 2.5

  b) 6.25

Step-by-step explanation:

For similar figures, the ratio of any corresponding linear dimensions is the same. The ratio of areas is the square of that.

<h3>Application</h3>

The ratio of linear dimensions, larger to smaller, is ...

  (30 yd)/(12 yd) = 2.5

<h3>a) Perimeter</h3>

Perimeter is a linear dimension, the sum of side lengths. The ratio of perimeters is 2.5.

<h3>b) Area</h3>

The ratio of areas, larger to smaller, is the square of the scale factor for side lengths:

  (2.5)² = 6.25

The ratio of the areas of the larger to smaller figure is 6.25.

Three people share half a pizza evenly. What fractional part of the original pizza does each one get?
beks73 [17]

Answer:

The fractional part of the original pizza is  \frac{1}{6}

Step-by-step explanation:

Let

x-----> the original pizza (complete pizza)

we know that

Half a pizza represent ------> \frac{x}{2}

Divide half a pizza by three people

(\frac{x}{2})/3=\frac{x}{6}

therefore

The fractional part of the original pizza is  \frac{1}{6}
