I need the explanation and the answer of 14/40 in simplest form
Korvikt [17]

Answer:

\frac{7}{20}

Step-by-step explanation:

To simplify a fraction, you need to find the GCF (Greatest Common Factor) of the numerator (top number) and denominator (bottom number).

Factors of 14:

1, 2, 7, 14

Factors of 40:

1, 2, 4, 5, 8, 10, 20, 40

As you can see, 2 is the GCF of 14 and 40. So, we now divide both numbers by 2.

14 ÷ 2 = 7

40 ÷ 2 = 20

Therefore, \frac{14}{40} in simplest form is \frac{7}{20}

how many triangles can you make with the given lengths of three line segments are 4 centimeters, 5 centimeters, and 9 centimeter
netineya [11]
None.  The triangle inequality states that the sum of the smaller two sides of a triangle must be greater than the third side.  As 4+5=9, this inequality is false in this case, so these sides cannot create a triangle.

Algebra 2 question need help.​

Answer: Choice C

h(x) = -x^4 + 2x^3 + 3x^2 + 4x + 5

===========================================

Explanation:

When reflecting the function f(x) over the y axis, we replace every x with -x and simplify like so

f(x) = -x^4 - 2x^3 + 3x^2 - 4x + 5

f(-x) = -(-x)^4 - 2(-x)^3 + 3(-x)^2 - 4(-x) + 5

f(-x) = -x^4 + 2x^3 + 3x^2 + 4x + 5

h(x) = -x^4 + 2x^3 + 3x^2 + 4x + 5

Note the sign changes that occur for the terms that have odd exponents (the terms -2x^3 and -4x become +2x^3 and +4x); while the even exponent terms keep the same sign.

The reason why we replace every x with -x is because of the examples mentioned below

-----------

Examples:

The point (1,2) moves to (-1,2) after a y axis reflection

Similarly, (-5,7) moves to (5,7) after a y axis reflection.

As you can see, the y coordinate stays the same but the x coordinate flips in sign from negative to positive or vice versa. This is the direct reason for the replacement of every x with -x.
