angle measure ------- part of circle
$90^0 - -----\frac14\n x \ \ ------\frac3{20}\n \n \frac14x=90^0\cdot\frac3{20}\n \frac14x=(270)/(20)\n \frac14x=\frac{27}2\ \ \ \ |\cdot4\n x=\frac{27}2\cdot4\n x=\frac{108}2\n \boxed{x=54\ degrees}$

Solve x2 + 4x − 12 = 0.A: x = 2, x = −6
B: x = −2, x = −6
C: x = 3, x = −4
D: x = −3, x = 4

Answers

x^2 + 4x - 12 = 0
(x + 6)(x - 2) = 0

x + 6 = 0 x - 2 = 0
x = -6 x = 2

Answer A: x = 2; x = -6

Answer:

x = - 6; x = 2

How many lines of symmetry does the figure below appear to have a heart?

Answers

The heart one lines of symmetry.

What is Line of symmetry?

If an object can be divided into two identical halves, it is said to have symmetry in mathematics. The term "line of symmetry" refers to the line that splits an object into two identical halves.

For instance, the symmetry line of the flower in the above image is the line that runs through its Centre.

Given:

We have the shape of Heart.

The line of symmetry can be categorized based on the basis of its orientation.

Vertical Line of Symmetry is a vertical line is said to be vertical if it splits an object into two identical halves.

This indicates that an object is divided into its mirror halves along a vertical line that runs from top to bottom (or vice versa).

So, the figure of heart have oneline of vertical symmetry.

2(6x - 4)(x - 1) = 0
2(x - 1)(3x - 4) = 0

Answers

6x^2 - 14x + 8 = 0
2(3x^2 - 7x + 4) = 0
2(3x^2 - 3x - 4x + 4) = 0
2(3x(x - 1) - 4(x - 1)) = 0
2(x - 1)(3x - 4) = 0
