<h3><u>Question:</u></h3>

f(x) = 3x^2 + 4x – 8.

How many zeros does this have?

<h3><u>Answer:</u></h3>

The given function has two zeros

<h3><u>Solution:</u></h3>

According to the "Fundamental Theorem of Algebra", a polynomial of degree "n"  has  "n"  zeroes

Regardless of odd or even, any polynomial of positive order can have a maximum number of zeros equal to its order. For example, a cubic function can have as many as three zeros, but no more. This is known as the fundamental theorem of algebra.

The degree is the value of the greatest exponent of any term (except the constant ) in the polynomial.

Your function is second degree polynomial, so it has two zeroes.

These can be a mix of rational, irrational, and complex zeroes.

Answer:

x = 10

Step-by-step explanation:

it has 8 sides so:

total interior angle degrees = (180° x 8 sides) - 360° = 1080°

11x + 14 + 4x + 87 +2x + 70 + 4x + 31 + x + 92 + 3x + 167 + 5x + 48 + 2x + 251 = 1080°

combine like terms:

32x + 760° = 1080°

subtract 760° from both sides of the equation:

32x = 320°

divide both sides by 32:

x = 10

PLEASE PLEASE HELP 30 POINTS AND WILL GIVE BRAINIEST
olga2289 [7]

Answer:

Please read down below, thanks

Step-by-step explanation:

Vertical angles are always equal.

Because the two expression we have are equal, we can make the equation:

4x + 2 = 5x - 13

Let's move x to one side and the constants to the other side.

Subtract both sides by 4x and add both sides by 13

15 = x

Now we know x = 15, we can solve for the angles.

∠ABC is 4x + 2 so: 4(15) + 2 = 47 degrees

∠CBE added up with ∠ABC is 180 degrees so: 180 - 47 = 133 degrees

∠DBE is the same as ∠ABC so: 47 degrees

∠ABD is also the same as ∠CBE so: 133 degrees
