Answer:
[tex]x=2,\\x=-2,\\x=\sqrt{3},\\x=-\sqrt{3}[/tex]
Step-by-step explanation:
This is a quadratic in disguise. Let [tex]n=x^2[/tex]. We can rewrite the problem as a quadratic to solve:
[tex]n^2-7n+12=0,\\(n-3)(n-4)=0,\\n=3,\: n=4[/tex].
Now plug in these values of [tex]n[/tex] to solve:
[tex]\begin{cases}x^2=4, \:x=\pm 2\\\\x^2=3, x=\pm\sqrt{3}\end{cases}[/tex].
Therefore, our solutions are [tex]x=\pm 2, \:x=\pm\sqrt{3}[/tex].

Answer:
The point-slope form of the equation of a line is ...
y -h = m(x -k)
for a line with slope m through point (h, k).
Comparing this to the given equation, you see that ...
h = -2, m = 1, k = -4
The line has a slope of 1 and goes through the point (-4, -2). This information is useful for graphing.
__
You can also rearrange the equation to slope-intercept form by subtracting 2 from both sides.
y = x +2
This has a slope of 1 and crosses the y-axis at y=2. It graphs the same as the above.
The graph of 4x + 2y < 3 is the region below the line 4x + 2y = 3.
The graph is given below.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
The graph of 4x + 2y < 3 is the region in the coordinate plane that satisfies the inequality.
To graph this inequality, we can start by graphing the line 4x + 2y = 3.
This line has a slope of -2 (because it can be written in the form
y = (-2x/1) + (3/2)), and a y-intercept of (0, 3/2).
We can plot this point on the y-axis and use the slope to find other points on the line.
For example, if we move one unit to the right from the y-intercept, we will move down two units (since the slope is -2), giving us the point (1, 1/2). Similarly, if we move one unit to the left from the y-intercept, we will move up two units, giving us the point (-1, 5/2).
We can connect these points to graph the line.
Therefore,
The graph of 4x + 2y < 3 is the region below the line 4x + 2y = 3.

Answer:
Length
√45 units
Distance
√13 units
Step-by-step explanation:
Here, we want to calculate the length and the distance between the points
To calculate the length, we need the coordinates of the points
These are;
(1,-2) and (4,4)
the length can be calculated using the formula for the distance between two points
Mathematically, that will be;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(1-4)^2 + (-4-2)^2
D = √(9 + 36)
D = √45 units
We use the same formula to get the distance between the two given points
that will be;
D = √(5-3)^2 + (-2-1)^2
D = √(2)^2 + (3)^2
D = √13 units
y= 3x +5
