and
absolute value makes whatever is inside positeive
aka
|smileyface|>0
remember that


to solve
|x|=y
assume
x=y and
x=-y
(reason is because |-x|=|x|)

6 times abasolute value of n +3=-9 is it translated to words

6|n|+3=-9
move over, minus 3 both sides
6|n|=-12
divide both sides by 6
|n|=-2
false, absolute value makes it positive
-2 is not positive


no solution

Answers

Answer: Joey's answer should be a square.

Step-by-step explanation:  Given that Joey is asked to name a quadrilateral which is also a rhombus. We are to find Joey's answer.

Rhombus :  a quadrilateral having all the four sides equal and diagonals bisect each other perpendicularly.

We know that the only quadrilateral having four equal sides and diagonals bisecting each other perpendicularly is a SQUARE.

Also, a square has all angles as right-angles in addition.

Therefore, Joey's answer should be a square.
His answer should be a square because a square is a parallelogram with four similar sides and four right angles. A quadrilateral is a square if its a rhombus and/or rectangle.

A floor of a room is in the shape of square. It is to be covered with rectangular tiles that each have an area of 192 square inches.If the length of the floor is 14 feet, how many tiles are needed to cover the floor?

Answers

If the length of the floor is 14 feet, convert it into inches to match the units of the tile. 14 feet is 168. So the floor is 168 inches long. Because we know it's a square and all sides are the same length, find the area of the floor by doing 168x168. This equals 28224 square inches. Then, divide by the area of one tile. 28224/192=147. So you need 147 Tiles.
