If (x²- 4) = (x + 2) = x - 2, which polynomial should fill in the blank below?
(x + 2)x____= x² - 4
O x² – 4
OX-2
O x + 2
O x²-2

Answers

Answer:

x-2

Step-by-step explanation:

(x+2)× ___=(x+2)(x-2)

___=(x+2)(x-2)/(x+2)

___=x-2

The polynomial which should be filled in the blank is (x - 2).

What are Polynomials?

Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.

Given that,

x² - 4 = (x + 2) (x - 2).

We have to find the blank space.

By commutative property, the other side is also equal.

That is,

(x + 2) (x - 2) = x² - 4

Hence the correct option is (x - 2).

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the given function is:

f(x) = -6 x 7.5x

We can rewrite this in the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept:

f(x) = -6 x 7.5x + 0 (since the x-term has a coefficient of 0)

f(x) = -45x + 0

So, the slope of the line is -45 and the y-intercept is 0.

Therefore,

The value of the y-intercept is 0.

y = 0

How many flowers, spaced every 4 in., are needed to surround a circular garden with a 100-ft radius?

Answers

Answer:

1885 flowers

Step-by-step explanation:

Given that:

Radius, r of circle = 100 feets

The Circumference of the circke is thus ; 2πr

C = 2 * π * 100

C = 628.31853 feets

Converting feets to inches

1 foot = 12 inches

628.31853 feets = 628.31853 * 12 = 7539.8223 inches

If flowers are spaced at 4 inches :

Number of flowers that can be planted :

Circumference of circle / spacing

7539.8223 / 4

= 1884.9555 flowers

= 1885 flowers

A regular 13-gon is inscribed in a circle. Find the measure of each are intercepted by the sides of the polygon. Round your answer to the nearest hundreth of a degree.

Answers

Answer:

The measure of the angle subtended by each arc intercepted by the sides of the reh13-gon is approximately 27.69°

Step-by-step explanation:

The number of of equal sides in a regular 13-gon = 13 sides

The measure of the angle, 'θ', subtended by each arc intercepted by the sides of the 13-gon is given as follows;

θ = 360°/13 = [tex]27\dfrac{9}{13} ^{\circ}[/tex]  

By rounding rounding the answer to the nearest 10th, we have that the measure of the angle subtended by each arc intercepted by the sides of the 13-gon, θ = [tex]27\dfrac{9}{13} ^{\circ}[/tex] ≈ 27.69°
