Explain this please!

435 ft

Step-by-step explanation:

area of triangle:

A = (b x h) : 2

A = (15 x 4) : 2

A = 60 : 2

A = 30 ft

area of rectangle:

A = b x h

A = 25 x 15

A = 375 ft

area of the yard = area of the triangle + area of the triangle + area of the rectangle (Here, both triangles have the same area.)

area of the yard: 30 + 30 + 375 = 435 ft.

So, the area of the yard is 435 ft.

I hope this was helpful. :)

The points (8 ,6) and (9 , 7) are solutions of the system of inequalities ⇒ C and D

Step-by-step explanation:

Let us study each inequality and find the right solutions

∵ x > 2

∴ The x-coordinates of the points are 3, 6, 7, 8, 9

- That means answer A is out because its x-coordinate not greater

  than 2 ⇒ (-3 , 8)

∵ y > 5

∴ The y-coordinates of the points are 6, 7, 8

- That means answers B and F are out because y-coordinates

   of them not greater than 5 ⇒ (7 , 5) , (3 , 2)

∵ y < x

∴ The x-coordinate of the point is greater than the y-coordinate

- That means answer E is out because its x-coordinate is equal to

   the y-coordinate ⇒ (6 , 6)

∴ The points are (8 , 6) and (9 , 7) because their x-coordinates

   are greater than 2, their y-coordinates are greater than 5 and

    their y-coordinates are less than their x-coordinates

The points (8 ,6) and (9 , 7) are solutions of the system of inequalities
