Which of the following is equivalent to (X - 2) (x + 9) =0
The equivalent quadratic equation to (x - 2)(x + 9) = 0 is x² + 7x - 18 = 0.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
We know if α and β are the roots of a quadratic equation ax² + bx + c = 0,
Then we can construct the equation by the factors (x - α)(x - β).
Given, We have to construct a quadratic equation with (x - 2)(x + 9) = 0.
Now, Multiply the terms we have,
x² + 9x - 2x - 18 = 0.
x² + 7x - 18 = 0.
So, Our required quadratic equation is x² + 7x - 18 = 0.

What governs motion, according to Newton?The motion of an object is related to the forces acting on it by Newton's laws of motion. According to the first law, unless a force acts on an object, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction forces upon one another.
Solution:-

The perimeter of the rectangle is 4y + 6 (cm).
How can the perimeter equation be found?All four side lengths must be added up in order to get the perimeter, or the distance around the rectangle. Since there are two of each side length, it is simple to multiply the total of the length and the breadth by two in order to do this task effectively. The formula for perimeter is perimeter=(length Plus width)2.

PROBLEMA DE NUMEROS ENTEROS : Un buzo se encuentra a 4000 metros de profundidad. ¿Si desciende 2000 metros para atrapar mantarrayas, a que profundidad del nivel del mar se encuentra?
Answer:
Tras descender 2000 metros para atrapar mantarrayas el buzo se encontrará a 6000 metros bajo el nivel del mar.
Step-by-step explanation:
Dado que un buzo se encuentra a 4000 metros de profundidad, si desciende 2000 metros para atrapar mantarrayas, para determinar a que profundidad del nivel del mar se encuentra se debe realizar el siguiente cálculo:
4000 - 2000 = X
6000 = X
Por lo tanto, tras descender 2000 metros para atrapar mantarrayas el buzo se encontrará a 6000 metros bajo el nivel del mar.

Answer:
g(-3) = 2
Step-by-step explanation:
g(x) = |x| - 1, x < 1 You would use this equation for finding g(-3). Since -3 is less than 1.
g(x) = |x| - 1, x < 1 ← You can ignore the x<1 part.
g(-3) = |-3| - 1 Input the value -3 as x. The absolute value of x is always g(-3) = 3 - 1 positive.
g(-3) = 2 Simplified
Next,
g(x) = x²- 10, 1 ≤ x ≤ 3 You would use this equation for finding g(3). Since 3 is equal to 3.
g(x) = x²- 10, 1 ≤ x ≤ 3 ← You can ignore the 1 ≤ x ≤ 3 part.
g(3) = (3)²- 10 Input the value 3 as x.
g(3) = 9 - 10 Simplify
g(3) = - 1
Then,
g(x) = [tex]\frac{1}{6}[/tex]x, x > 3 You would use this equation for finding g(6). Since 6 is greater than 3.
g(x) = [tex]\frac{1}{6}[/tex]x, x > 3 ← You can ignore the x > 3 part.
g(6) = [tex]\frac{1}{6}[/tex](6) Input the value 6 as x.
g(6) = [tex]\frac{6}{6}[/tex] Simplify
g(6) = 1
Answer: g(-3) = 2 results in the largest value/output.

What is a 12-hour Clock system?On an analogue clock, the 12-hour clock is most frequently displayed as the digits 1 through 12; on a digital clock, it is typically followed by either a.m. (ante meridiem, Latin for "before noon") or p.m. (post meridiem, Latin for "after noon").
What is a 24-hour Clock system?Digital clocks are more frequently used to display the 24-hour clock, which is printed in a 4-digit format with the first two numbers denoting the hour and the final two denoting the minutes.
No need for a.m. or p.m. is necessary because each time represents one of the 24 hours in a day. For instance, 0300 is the third hour of the day, or 3am; 1400 is the fourteenth hour of the day, or 2pm; and 1830 is the thirty-minute mark after the eighteenth hour of the day, or 6.30pm.
How can we change 12-hour time format into a 24-hour clock format?Children can be taught to add 12 to the hours after noon in order to change a 12-hour clock to a 24-hour one. For instance, 3pm becomes 15:00 since 3 + 12 = 15.

Find the value of x.
Use statement and reason format.
By using properties for angles we can find and solve some linear equations, there we can see that x = 30°.
How to find the value of x?Remember that the sum of the interior angles of a triangle must give 180°, and we also know that the angle defined by a line is 180°.
Let's define N as the angle located at vertex N of the right triangle in the left side, we then can write:
2x + 90° + N = 180°
And we also can write the linear equation:
105° + 45° + N = 180°
Solving this one, we can find the value of N.
N = 180° - 45° - 105° =30°
N = 30°
Replacing that in the equation with x we will get:
2x + 90° + 30° =180°
2x = 180° - 90° - 30°
2x = 60°
x = 60°/2 = 30°
The value of x is 30°.
