Answer:

Step-by-step explanation:

Using Cramer's rule to find the values of x and y, there are 3 different values that we need to calculate, they are D, Dx, and Dy. In all 3 cases the “D” stands for the determinant

D = Determinant of x and y values in 2 x 2 matrix

x = Dx/D and y = Dy/D, here we replace x and y values with the values after the equal sign respectively

x = 29/58 = 1/2

y = -29/58 = -1/2

Vinyl peel and-and-stick floor tiles are each 1- foot square. What is the minimum number of these tiles needed to tile the entir
Anna [14]

Answer:

The minimum number of Vinyl peel and stick floor tiles needed is 216 Tiles

Step-by-step explanation:

Here we have area size of Vinyl peel and stick floor tiles = 1 ft²

Size of floor of rectangular room = 12 ft × 14 ft = 168 ft²

Size of floor on rectangular hallway = 12 ft × 4 ft = 48 ft²

Total area of floor in rectangular room and rectangular hallway

= 168 ft² + 48 ft² =  216 ft²

Therefore number of Vinyl peel and stick floor tiles needed =

(Total area of floor in rectangular room and rectangular hallway)÷( Area size of Vinyl peel and stick floor tiles) = 216 ft²/(1 ft²) =  216

Therefore the minimum number of Vinyl peel and stick floor tiles needed =  216 Tiles.

For the question: "My quadrilateral has a pair of equal sides and a pair of parallel sides, what special type my quadrilateral m
Effectus [21]

Answer:

Step-by-step explanation:

It must be a trapezoid because a trapezoid has at least one set of parallel sides.  Sides of equal length don't mean anything really unless we know hose sides are parallel.  I will say sometimes I hear trapezoids ONLY have two parallel sides, while the other two are not, while in other places as long as two are parallel it is a trapezoid.  It looks like for this question it is using the definition that at least two parallel sides makes it a trapezoid.

it can be an isosceles trapezoid since it is a type of trapezoid,  same with right trapezoid.  Basically any special kind of trapezoid

parallelogram because it can have two pairs of parallel lines and have thos parallel sides be equal.  So this also means it can be all kinds of parallelograms.  

Do you have a list to choose from?  because most I pull up don't include right trapezoid at least.

This leaves kite as the only kind of quadrilateral to look at yet, and it specifies no parallel sides. bt your shape need at least one set of them, so it cannot be a kite.
