Drupady [299]2 years ago

Answer:

x = 111

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7 , then

sum = 180° × 5 = 900

Sum the interior angles and equate to 900

x + 139 + 121 + 125 + 126 + 158 + 120 = 900

x + 789 = 900 ( subtract 789 from both sides )

x = 111

Write the standard equation for the circle.
Sidana [21]

Answer:

the first one

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (10, - 6) and r = 6, hence

(x - 10)² + (y - (- 6))² = 6², that is

(x - 10)² + (y + 6)² = 36

If a polynomial cannot be written as the product of two other polynomials​ (excluding 1 and minus−​1), then the polynomial is sa
Anni [7]
In mathematics, a polynomial is an algebraic expression containing more than two terms. When the polynomial could not be reduced to a lower degree, it is classified as a prime polynomial. Just like whole numbers, a prime polynomial cannot be broken down into factors except 1 and by the number itself. Take for example, the polynomial x² + 5x + 6. It can be reduces to its factors x=-2 and -3. That would be expressed to x² + 5x + 6 = (x+2)(x+3). But if the polynomial is, say, x² + 5x + 7, there is no roots that are whole numbers. Therefore, it can't be reduced into factored groups because it is a prime polynomial.

Find the equation of a line that has the same slope ask why equals 10-4x and the same Y intercept is why equals -9x-8
Alborosie

Answer:

y=-4x-8

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

so

1) Find the slope of the given line y=10-4x

The slope is m=-4

2) Find the y-intercept of the given line  y=-9x-8

The y-intercept is b=-8

therefore

The equation of the line with

m=-4

b=-8

is equal to

y=-4x-8

Find the percent of change round to the nearest percent original 32.5 new:30
tatuchka [14]
Percent change = ((new value) - (old value))/(old value) × 100%
  = (30 - 32.5)/32.5 × 100%
  ≈ -8%
