<h3>Answer: No real solutions</h3>

Note: this is assuming you haven't reached complex numbers yet

=============================================================

Explanation:

The given equation 13u^2+23u = -112 is the same as 13x^2+23x = -112

and we can add 112 to both sides getting 13x^2+23x+112 = 0

We see the equation is in the form ax^2+bx+c = 0

The discriminant is

D = b^2 - 4ac

D = 23^2 - 4(13)(112)

D = -5295

The negative discriminant means there are no real number solutions.

-----------

Extra info:

If D = 0, then there would be exactly one real number solution.

If D > 0, then there would be two distinct real number solutions.

Answer:

it is complex solution

no real number solution

Step-by-step explanation:

13u²+23u=-112

13u²+23u+112=0  

a=13, b=23 , c=+112

u= (-b±√(b²-4ac))/2a

u=[(-23±√(23)²-4(13)(112)]/2(13)

u=(-23±√-5295)/26

u=(-23±i√5295)/26

Answer:

First of all, I expect you fulfill your word and give what you promise... ha ha just kidding, I already solved a question like this one, please see below explanation.

1. Tessellation is the covering of a surface with pattern(s) of flat shapes so that there are no overlaps or gaps. It is also called Tiling.

2. Triangles, Squares, and Hexagons are regular polygons.

3. Previous three shapes create a regular tessellation pattern because all their sides and all their angles are the same. the intersection point of the interior angles is called "Vertex". For a regular tessellation, the pattern is identical at each Vertex.

Unlike the triangle and quadrilateral case, the Pentagon's angle sum of 540° is not helpful when trying to fit a bunch of Pentagons around a vertex. Therefore, even though the Pentagon is a regular polygon, it cannot tessellate.

4. See attached screenshot of 3 tessellations created with Tessellation Artist Software online.

Which values of c will cause the quadratic equation –x2 3x c = 0 to have no real number solutions? check all that apply.
nika2105 [10]

The given quadratic equation will not have any real solution for c<-9/4.

The given quadratic equation is:

-x^{2} +3x+c=0

<h3>What is a quadratic equation?</h3>

Any equation of the form ax^{2} +bx+c=0 is called a quadratic equation with a≠0.

In order to have no real solution, the discriminant of a quadratic equation will be less than zero.

D < 0

3^{2} -4(-1)(c) < 0

9+4c < 0

c < -\frac{9}{4}

For c < -\frac{9}{4} the given quadratic equation will have no real solutions.

Hence, the given quadratic equation will not have any real solution for c<-9/4.

A regular hexagon has an apothem of 14.7 inches and a perimeter of 101.8 inches. what is the area of the hexagon? square inches
WINSTONCH [101]

Answer:

748.23 in^2.

Step-by-step explanation:

Area = 1/2 * apothem * perimeter

        = 1/2 * 14.7 * 101.8

        =  748.23 in^2.

What is the 31st term in the sequence below?<br> -108,-90,-72,-54
Anna71 [15]
Add 18 each time
first term is -108

an=a1+d(n-1)
d=common difference
a1=startng term

an=-108+18(n-1)

31 term
a31=-108+18(31-1)
a31=-108+18(30)
a31=-108+540
a31=432


31st term is 432
