Answer:
a) 2x² - x + 3 = x(2x + 1) - 2x
<=> 2x² - x + 3 = 2x² + x - 2x
<=> 3 - x = - x
<=> 3 = 0
=> no solution
b) x/2 - x/3 - x/4 = 1/12
=> the euqation has the solution x = 1
c) |x - 5| = 2|x|
=> x - 5 = 2x
or x - 5 = -2x
<=> x = -5
or 3x = 5
<=> x = -5
x = -5or x = 5/3
d) defined conditions: 2 - x 》 0
<=> x 《 2
we have:
<=> x = 0 (because x 《 2)
e)
<=> x = -1/4
The tangent is the ratio of the perpendicular and the base of the right triangle. Then tan A will be x/y.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The right-angle triangle ΔABC is given.
The angle ∠C is 90°.
And the perpendicular is x, the base is y, and the hypotenuse is z.
Then the value of the tangent of angle ∠A will be
The tangent is the ratio of the perpendicular and the base of the right triangle.
tan A = x/y

Answer:
Area= 6
Perimeter= 10
Step-by-step explanation:
The area is length x width, which in this case would be 3 x 2, giving the area of 6.
The perimeter is length + length + width + width, which in this case would be 3 + 3 + 2 + 2, giving the perimeter of 10.
Hope this helps :)!
