<span>kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.

a square does fir this definition since it has 4 equal sides, hence 2 pairs and hte equal sides are adjacent to each other.
so yes a square is a kite

the definition of a rectangle is </span>
<span>a figure with four straight sides and four right angles, </span>

a parallelogram with 4 right angle woudl be a rectangle but any without would not

so it can be, but generally is not

What is the area of polygon LMN? <br><br> A. 50<br> B. 60<br> C. 65<br> D. 70<br> E.80
Verdich [7]

Answer:

c:65

Step-by-step explanation:

The area of a triangle can be found almost the same way as a sqaure L*W (Length times width). Except the area of a triangle is one half that of a square, so it is \frac{1}{2}L*W. The length is 13 and the width is 10, so 13*10=130, than 1/2 that is 65.

Find all solutions to the equation. cos^2x + 2 cos x + 1 = 0
Black_prince [1.1K]

Answer:

x = pi, 3pi, 5pi  etc

x = -pi, -3pi, -5pi etc

Step-by-step explanation:

cos^2 x + 2 cos x + 1 = 0

replace cos x with m

m^2 + 2m +1 = 0

solve by factoring  (this is a^2 +2ab+b^2 = (a+b)^2  where a =m and b=1)

(m+1)^2=0

take the square root of each side

m+1 =0

m=-1

now replace m with cos x

cos x = -1

take arccos  of each side

arccos cos x = arccos (-1)

x = pi, 3pi, 5pi  etc

Let me know the answer plz
irinina [24]

Answer:

J

Step-by-step explanation:

Find the common ratio r of the geometric sequence then multiply a term by r to obtain the next term

r = \frac{a_{2} }{a_{1} } = \frac{6}{-36} = - \frac{1}{6}

The next 3 terms are

\frac{1}{6} × - \frac{1}{6} = - \frac{1}{36}

- \frac{1}{36} × - \frac{1}{6} = \frac{1}{216}

\frac{1}{216} × - \frac{1}{6} = - \frac{1}{1296}

Perform the indicated operation to write given polynomial in standard form: (x^3+2x^2 − 3x − 1) +(4 − x − x^3)
Rzqust [24]

Answer:

\left(x^3+2x^2-3x-1\right)+\left(4-x-x^3\right)=2x^2-4x+3

Step-by-step explanation:

To write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to write.

To add the polynomials you need to:

Remove parentheses

\left(x^3+2x^2-3x-1\right)+\left(4-x-x^3\right)=x^3+2x^2-3x-1+4-x-x^3

Group like terms

\left(x^3+2x^2-3x-1\right)+\left(4-x-x^3\right)=x^3-x^3+2x^2-3x-x-1+4

Add similar elements

\left(x^3+2x^2-3x-1\right)+\left(4-x-x^3\right)=2x^2-3x-x-1+4\\\left(x^3+2x^2-3x-1\right)+\left(4-x-x^3\right)=2x^2-4x-1+4\\\left(x^3+2x^2-3x-1\right)+\left(4-x-x^3\right)=2x^2-4x+3
