Answer:

x=7

Step-by-step explanation:

We have been given all exterior angles of a quadrilateral which is a polynomial having 4 sides


We know that sum of all exterior angles of a regular polygon is always 360 degree.

So we can all given exterior angles and set it equal to 360


(12x+37)+(12x-2)+(46)+(20x-29)=360

12x+37+12x-2+46+20x-29=360

12x+12x+20x+37-2+46-29=360

44x+52=360

44x=360-52

44x=308

divide both sides by 44

x=7

<u>Hence final answer is x=7.</u>

denis-greek [22]

Answer:

26 1-foot squares of silver paper.

Step-by-step explanation:

The dimensions of the bulletin board are  6.5 feet by 4 feet.

To determine how many squares of silver paper she needs to but, we first determine the area of the bulletin board.

Area of the board =6.5 X 4= 26 Square feet

Therefore, Mrs Golden needs to buy <u>26 1-foot squares of silver paper.</u>

There will be <u>no pieces left over</u> as there is no decimal or fractional value in the area of the bulletin board.

Potential roots of p(x) = x^4 - 9x^2 - 4x + 12
lubasha [3.4K]

Answer:

-6, -4, -3, -2, -1, 1, 2, 3, 4, 6

Step-by-step explanation:

The general formula for a fourth-degree polynomial is

f(x) = ax⁴ + bx³ + cx² + dx + e

Your polynomial is  

f(x) = x⁴ - 9x² - 4x + 12

a = 1; e = 12

According to the Rational Roots Theorem, the possible rational roots are the factors of e divided by the factors of a.

Factors of e = ±1, ±2, ±3, ±4, ±6

Factors of a = ±1

Potential roots are x = ±1 ±2, ±3, ±4 ± 6

Putting them in order, we get the potential roots

x = -6, -4, -3, -2, -1, 1, 2, 3, 4, 6

(The graph of your function shows roots at x = -2, x = 1, and x = 3.)
