Answer:

The value of 2x - (3x +2x) is

$2x -(3x + 2x)\\= 2x - 3x - 2x \\= \boxed{ - 3x}$

<h3><u>-3x</u> is the right answer.</h3>

N=3, zeros 4 and 2i, f(2)=-48 find nth degree polinomonal function

enot [183]

The degree is 3, the zeros are; 4, 2i, -2i and a point is (-48, 2)

For zeros; 2i, -2i <-- complex conjugates, always in pairs

$\frac{c}{a}=(2i)(-2i) 
$
= -4(i²=-1)
=5

$\frac{b}{a}=-(2i+(-2i))$
=0

Therefore the equation is; a( $x^{2}$ +5) <-- b value is zero

Rewrite the equation with all zeros;

a(x-4)(x²+5)=f(x) <-- put in coordinates of the points to find the value of x
a(2-4)(2²+5)=-48
a(2)(9)=-48
a=-48/18
a=-8/3

The final polynomial function is; (-8/3)(x-4)(x²+5)=f(x)

Hope I helped :)

What is the measure of one of the interior<br>angles of the regular quadrilateral?

creativ13 [48]

Answer:

<em>Measure of one of the interior angles ⇒ 90°</em>

Step-by-step explanation:

If we are considering a regular polygon, all sides are ≅, respectively all angles are ≅ as well;

Now any quadrilateral has total interior angle measure of 360 degrees, provided they each can be split into two triangles and hence knowing a triangle is 180 degrees each, ⇒ 180 * 2 = 360°;

So if all these angles are ≅, we can claim that;

m∠ 1 = m∠ 2 = x = m∠ 3 = m∠ 4, where ∠1, 2, 3, and 4 are interior angles

x + x + x + x = 360 degrees ( ° ),

4x = 360°,

x = 90° = m∠ 1 = m∠ 2 = m∠ 3 = m∠ 4,

<em>Solution; Measure of one of the interior angles⇒ 90°</em>

Im not good with least to greatest in fractions, Please help me

tiny-mole [99]

Answer:

From least to greatest it is -5/2, -2, then 1.7

Step-by-step explanation:

First by process of elimination, 1.7 is the only positive number, so it is the greatest number compared to the other two.

Now we are left with -2 and -5/2.

We can rewrite -2 as $-\frac{2}{1}$ , as any number by itself itself is the number over 1.

Then we need to find the common denominator for both fractions, meaning they must share the same bottom number.

The 1 in the denominator can be multiplied by 2 to get a denominator of 2 , the same as the denominator for $-\frac{5}{2}$ .

Since the denominator is multiplied by 2, the numerator also has to be multiplied by 2:

$-\frac{2}{1} *\frac{2}{2}$ $=-\frac{4}{2}$

Now since both fractions share the same denominator, we can compare them by their numerators. 5 is greater than 4, but we must keep in mind that these are negative. The larger the negative number, the smaller the value.

So when comparing -4/2 and -5/2, -5/2 is smaller.

So our final answer from least to greatest is -5/2, -2, then 1.7
