The diagram shows a tile in the shape of a trapezium.
Ann [662]

Answer:

286cm²

Step-by-step explanation:

Let the parallel sides be 12cm and 10cm

Height h = 26cm

Area of a trapezium = 1/2(a+b) * h

Area of a trapezium = 1/2(12+10)* 26

Area of a trapezium = 1/2(22)*26

Area of a trapezium = 11 * 26

Area of a trapezium = 286cm²

Hence the area of the tiles is 286cm²

Graph the solution of the system of linear inequalities.<br> y≤−4x−4<br> y≥x+2
tamaranim1 [39]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y\leq -4x-4 ----> inequality A

The solution of the inequality A is the shaded area below the solid line y=-4x-4

The y-intercept of the solid line is -4

The x-intercept of the solid line is -1

The slope of the solid line is negative

y\geq x+2 ----> inequality B

The solution of the inequality B is the shaded area above the solid line y=x+2

The y-intercept of the solid line is 2

The x-intercept of the solid line is -2

The slope of the solid line is positive

The solution of the system of inequalities is the shaded area between the two solids line

see the attached figure
