The sum of the measures of the interior angles of a polygon is 2880°. How many sides does the polygon have?14

20

Answers

Let

S------> The sum of the measures of the interior angles of a polygon

n-------> number of sides of a polygon

we know that

The formula to find the sum of the measures of the interior angles of a polygon is equal to

$S=(n-2)*180$ °

in this problem

$S=2880$ °

Solve for n

$S=(n-2)*180\n \n n=(S)/(180)+2\n \n n=(2880)/(180)+2\n \n n=16+2\n \n n=18\ sides$

therefore

the answer is

$18\ sides$

there are 18 sides.....

Diagram shows a section of a bridge between the points A and K. The length of line segment is 640 meters. ∆ABC, ∆CDF, and ∆FJK are similar, and 2AC = CF = 2FK. The first pillar, , is 20 meters tall.The area of ∆CDF is square meters.

Answers

AK = 640
Δ ABC and ΔFJK are similar. They are small triangles.
ΔCDF is the big triangle.

640 / 2 = 320 m= CF
AC & FK= 320/2 = 160 m each

2AC = CF = 2FK
2(160) = 320 = 2(160)

BG = 20 m

20/160 = x / 320
20*320 = 160x
6400 = 160x
6400/160 = x
40 = x

Area of CDF = (40 m * 320 m)/2 = 12,800 / 2= 6,400 m²

Subtract 2x 2 - 6x - 4
from 4x 2 - 4x + 3.

Answers

Subtracting the polynomials, 2x² - 6x - 4 from 4x² - 4x + 3 will give 2x² + 2x + 7

How to subtract polynomials?

Polynomials can have constants, variables and exponents, but never division by a variable.

Let's do the arithmetic of the polynomial.

4x² - 4x + 3 - (2x² - 6x - 4)

Therefore, let's open the bracket with the operator

4x² - 4x + 3 - 2x² + 6x + 4

let's combine the like terms

4x² - 2x²- 4x + 6x + 3 + 4

Therefore,

2x² + 2x + 7

Look at this sequence.95, 80, 65, 50,... Which function represents this sequence? A. a(n) = 110n - 15 B. a(n) = 15n + 80 C. a(n) = 95n - 15 D. a(n) = -15n + 95

Answers

Answer:

Hi,
answer A

Step-by-step explanation:

The sequence is an AP with first term equal 95 and common difference equal -15

$a_n=a_1+(-15)*(n-1)= 95+(-15)*(n-1)=95-15n+15\n\n\boxed{a_n=110-15n}\n$

Which expression is eqivalent to (x^2-3x)(4x^2+2x-9)

Answers

For this case we must find an expression equivalent to:

$(x ^ 2-3x) (4x ^ 2 + 2x-9) =$

We apply distributive property, term by term, taking into account that: $- * + = -\n- * - = +\nx ^ 2 * 4x ^ 2 + x ^ 2 * 2x-x ^ 2 * 9-3x * 4x ^ 2-3x * 2x + 3x * 9 =$

By definition we have to, to multiply powers of the same base, the same base is placed and the exponents are added:

$4x ^ 4 + 2x ^ 3-9x ^ 2-12x ^ 3-6x ^ 2 + 27x =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

$4x ^ 4-10x ^ 3-15x ^ 2 + 27x$

Answer:

An equivalent expression is: $4x ^ 4-10x ^ 3-15x ^ 2 + 27x$
