<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

<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

What is the value of x in the equation 2(x – 3) + 9 = 3(x + 1) + x?<br>x = <br>​
sukhopar [10]

Start with

2(x-3)+9=3(x+1)+x

Expand both parentheses by multiplying both terms by the number outside:

2x-6+9 = 3x+3+x

Sum like terms:

2x+3 = 4x+3

Simplify the "+3" on both sides:

2x = 4x

Subtract 2x from both sides:

2x=0

Divide both sides by 2:

x=0
